Fajita seasoning

- 1 tsp smoked paprika
- ½ tsp garlic powder
- ½ tsp onion powder

Instructions
1. Prepare the seasoning
- In a small bowl, combine chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, cayenne pepper (if using), salt and black pepper.
- Mix well and set aside.
2. Season the chicken
- Place the chicken strips in a medium bowl.
- Drizzle with 1 tbsp olive oil and sprinkle over about two-thirds of the fajita seasoning mix.
- Toss until the chicken is evenly coated. Let it sit while you prepare the vegetables.
3. Cook the chicken
- Heat a large skillet over medium-high heat.
- Add the seasoned chicken strips in a single layer (cook in two batches if your pan is small).
- Cook for 4–6 minutes, stirring occasionally, until the chicken is nicely browned and cooked through.
- Transfer the cooked chicken to a plate and set aside.
4. Cook the vegetables
- In the same skillet, add the remaining 1 tbsp olive oil.
- Add the sliced bell peppers and onion.
- Sprinkle with the remaining fajita seasoning and add the minced garlic.
- Cook for 5–7 minutes, stirring often, until the vegetables are softened but still slightly crisp.
- Taste and adjust salt if needed.
5. Combine and add cheese
- Return the cooked chicken to the skillet with the vegetables.
- Toss everything together over medium heat for 1–2 minutes, just until heated through.
- Squeeze the juice of 1 lime over the mixture and stir.
- Spread the chicken and vegetables evenly in the skillet, then sprinkle shredded cheese over the top.
- Reduce the heat to low, cover the skillet with a lid and cook for 2–3 minutes, until the cheese is melted and bubbly.
6. Serve
- Remove from heat and garnish with chopped fresh cilantro.
- Serve directly from the skillet with warm tortillas, and add sour cream, salsa, guacamole or rice on the side if you like.
- Let everyone build their own fajitas at the table.
Tips & Variations
- Spice level:Â Reduce or skip the cayenne pepper for a milder dish, or add extra chili powder for more heat.
- Low-carb option:Â Skip the tortillas and serve the chicken fajita mixture over lettuce as a fajita salad, with avocado and extra veggies.
- Add vegetables:Â You can add sliced mushrooms, zucchini or corn to make it even more colorful and nutritious.
- Use thighs instead of breast:Â Boneless, skinless chicken thighs stay very juicy and work great in this recipe.
- Meal prep:Â Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in a skillet or microwave and use for fajita bowls, quesadillas or salads.
