1. Sheet-Pan Chicken Fajitas

My most-made weeknight meal. One pan, one cutting board, and the pan goes straight into the sink.

Prep: 10 min · Cook: 25 min · Serves: 4

Ingredients

• 1.5 lb (700 g) boneless chicken thighs, sliced into strips
• 3 bell peppers, sliced into strips
• 1 large onion, sliced
• 3 tbsp oil
• Juice of 1 lime
• 2 tsp ground cumin
• 2 tsp chili powder
• 1 tsp garlic powder
• 1 tsp salt
• 12 corn or flour tortillas, warmed, to serve

Steps

1. Heat the oven to 425°F (220°C). Slice the chicken, peppers, and onion into similar-sized strips so everything cooks at the same rate.
2. On the sheet pan, toss everything with the oil, lime juice, and seasonings. Spread in a single layer — crowding steams the vegetables instead of roasting them. Use two pans if needed.
3. Roast 20–25 minutes, stirring once halfway, until the chicken is cooked through and the vegetable edges are charred.
4. Serve straight from the pan with warm tortillas, salsa, and whatever garnishes you have.

2. Bean Tostadas (15 Minutes)

Canned refried beans are acceptable — if you doctor them.

Prep: 5 min · Cook: 10 min · Makes: 8 tostadas (serves 4)

Ingredients

• 8 corn tortillas
• 1 tbsp oil, plus more for brushing
• 1 can (16 oz) refried beans
• 2 tbsp salsa, plus more to serve
• 1/4 tsp ground cumin
• 2 cups shredded cabbage or lettuce
• 1 tomato, diced
• 1/2 cup crumbled queso fresco
• Crema or sour cream, to drizzle
• Optional: 4 fried eggs for protein

Steps

1. Crisp the tortillas: brush lightly with oil and bake at 400°F (200°C) for about 8 minutes, flipping once, until golden and rigid.
2. Doctor the beans: heat 1 tbsp oil in a skillet, add the beans, and stir in the salsa, cumin, and a splash of water to loosen. Fry, stirring, until they spread like soft butter.
3. Layer: beans first, then cabbage, tomato, cheese, and a drizzle of crema. Fried egg on top if you want it.

3. Quick Taco Bowls (20 Minutes with Pre-Cooked Rice)

Skip the tortilla, build a bowl. This is also the best destination for leftovers.

Prep: 10 min · Cook: 10 min · Serves: 4

Ingredients

• 4 cups cooked rice (cook it in broth with 1 tbsp tomato paste for color — or use Sunday’s batch)
• 1 lb (450 g) ground beef, or 3 cups shredded rotisserie chicken
• 1 tbsp oil (for ground beef)
• 2 tsp cumin, 1 tsp chili powder, 1/2 tsp garlic powder, 1/2 tsp salt (skip if using rotisserie)
• 1 can (15 oz) black beans, drained
• 1 cup corn (frozen is fine)
• 1/2 cup salsa, plus more to serve
• 1 avocado, sliced
• Lime wedges, cilantro

Steps

1. If using ground beef: brown it in the oil over medium-high, breaking it up, 6–7 minutes. Season. If using rotisserie chicken: shred it.
2. The key step: add the beans, corn, and salsa to the meat and warm together 2–3 minutes so everything is saucy, not dry.
3. Build bowls: warm rice, saucy meat and beans, avocado, extra salsa, cilantro, lime.

4. Chorizo and Potato Tacos (One Skillet)

Mexican chorizo is already seasoned — your work is done before you start.

Prep: 5 min · Cook: 15 min · Makes: 12 tacos (serves 4)

Ingredients

• 12 oz (340 g) Mexican chorizo (raw, not the Spanish cured kind), casings removed
• 3 medium potatoes, diced small
• 12 corn tortillas, warmed
• Salsa verde, to serve
• Diced onion and cilantro, to garnish

Steps

1. Head start on the potatoes: microwave the diced potatoes 4 minutes to soften.
2. Cook the chorizo in a hot dry skillet, breaking it up, until it crisps and renders its fat, 5–6 minutes.
3. Add the potatoes to the skillet and cook, stirring occasionally, until golden and coated in the chorizo fat, 7–8 minutes. That fat carries the whole dish.
4. Stuff into warm tortillas with salsa verde, onion, and cilantro.

5. Sopa de Lentejas (Mexican Lentil Soup)

Lentil soup doesn’t sound exciting. This one is — and it’s the healthiest, cheapest dinner on this list.

Prep: 10 min · Cook: 25 min · Serves: 4–6

Ingredients

• 1 tbsp oil
• 1/2 onion, diced
• 2 garlic cloves, minced
• 1 carrot, diced
• 1.5 cups brown or green lentils, rinsed
• 1 can (14.5 oz) diced tomatoes
• 5 cups chicken or vegetable broth
• 1 bay leaf
• 1 tsp salt (adjust to your broth)
• 1 tsp vinegar — the trick that wakes everything up
• Cilantro and lime wedges, to serve

Steps

1. Sauté the onion, garlic, and carrot in the oil over medium heat, 4 minutes.
2. Add the lentils, tomatoes, broth, bay leaf, and salt. Bring to a boil, then simmer, partially covered, 25 minutes until the lentils are tender.
3. Off the heat, stir in the vinegar and a handful of chopped cilantro. Taste — it should be bright, not flat.
4. Serve with warm tortillas and lime wedges.

My Weeknight Rules

• One pan or one pot. More than two pans, it waits for the weekend.
• Pre-cook the base. Rice, beans, or salsa made ahead turns dinner into a five-minute assembly job.
• Let the heat do the work. A properly hot skillet or a 425°F oven creates char and flavor that tastes like effort, even when there was none.

These meals are not fancy. They are honest, fast, and satisfying. That is what weeknight cooking should be.

FAQ

Which of these can I make entirely from the pantry? The lentil soup (swap the carrot for whatever vegetable you have) and the bean tostadas, if you keep tortillas in the freezer. Both use canned and dried staples.

What’s the difference between Mexican and Spanish chorizo? Mexican chorizo is raw, soft, and seasoned with chiles — it must be cooked and it crumbles as it fries. Spanish chorizo is cured and firm, like salami. For these tacos you need the Mexican kind; Spanish chorizo won’t render or crumble the same way.

Can I use chicken breast in the fajitas? You can, but reduce the roasting to about 18 minutes and check early — breast dries out fast at 425°F. Thighs are more forgiving and stay juicy, which is why I default to them.

How do I make the taco bowls vegetarian? Double the black beans and warm them with the salsa and corn, then add a fried egg or crumbled queso fresco on top. The bowl formula doesn’t change.

Which of these freeze well? The lentil soup freezes perfectly for 3 months. The chorizo-potato filling freezes well too — thaw and re-crisp in a skillet. Tostadas and bowls are assembly dishes; freeze the components, not the finished plate.
