Ingredients

Scale
  • 1.5 pounds boneless, skinless chicken breasts, sliced into strips
  • 3 bell peppers (red, yellow, and green), thinly sliced
  • 1 large yellow onion, thinly sliced
  • 2 tablespoons olive oil
  • 1 teaspoon chili powder
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon ground cumin
  • 1/2 teaspoon garlic powder
  • Salt and freshly ground black pepper, to taste
  • 2 ripe avocados
  • 1 lime, juiced
  • 1 small garlic clove, minced
  • 2 tablespoons finely chopped fresh cilantro
  • 1/4 cup finely diced red onion
  • Salt to taste
  • Optional: a pinch of cayenne pepper
  • Warm flour or corn tortillas
  • Sour cream or Greek yogurt (optional)
  • Sliced jalapeños or hot sauce (optional)

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Slice the chicken breasts into thin strips about 1/2 inch thick. Thinly slice the bell peppers and onion.
  3. In a large bowl, whisk together olive oil, chili powder, smoked paprika, cumin, garlic powder, salt, and pepper.
  4. Add the sliced chicken, peppers, and onion to the bowl and toss until well coated with the seasoning mix.
  5. Spread the chicken and veggies in a single layer on a rimmed sheet pan, avoiding overcrowding.
  6. Roast for 20-25 minutes until chicken reaches an internal temperature of 165°F (74°C) and peppers are tender with some charred edges. Toss halfway through cooking.
  7. While roasting, prepare the guacamole by mashing avocados with a fork until mostly smooth but slightly chunky. Stir in lime juice, minced garlic, cilantro, diced red onion, salt, and cayenne pepper if using. Keep chilled.
  8. Warm tortillas in a dry skillet over medium heat for 30 seconds per side or wrap in foil and warm in the oven for 5 minutes.
  9. Serve the roasted chicken and veggies with warm tortillas and a generous dollop of guacamole. Add sour cream or sliced jalapeños if desired.

Notes

If chicken looks dry, squeeze fresh lime juice over before serving. Toss ingredients halfway through roasting for even cooking. Use parchment paper or silicone baking mat for easier cleanup. Broil for 1-2 minutes at the end for crispier chicken but watch closely to avoid burning. For gluten-free, use corn tortillas. For dairy-free, skip sour cream or use coconut yogurt alternative. Fresh guacamole is best made just before serving; store with plastic wrap pressed on surface to minimize browning.
