Ingredients

Scale
  • 1.5 pounds boneless, skinless chicken breasts or thighs, cut into thin strips
  • 3 bell peppers (red, green, and yellow), sliced into strips
  • 1 medium yellow or white onion, thinly sliced
  • 2 tablespoons olive oil or avocado oil
  • 1 tablespoon chili powder
  • 1 teaspoon smoked paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon ground cumin
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon cayenne pepper (optional)
  • 2 tablespoons fresh lime juice
  • Fresh cilantro, chopped, for garnish (optional)
  • Flour or corn tortillas, warmed, for serving

Instructions

  1. Preheat your grill or oven to medium heat (about 400°F / 200°C).
  2. Slice chicken breasts or thighs into thin strips, about 1/2-inch thick. Slice bell peppers and onions into similar-sized strips.
  3. In a large mixing bowl, combine chili powder, smoked paprika, garlic powder, onion powder, cumin, salt, pepper, and cayenne. Add olive oil and fresh lime juice, then toss the chicken strips in the mixture until fully coated.
  4. Add the sliced bell peppers and onions to the bowl and toss gently to coat them with the seasoning mixture.
  5. Tear off large sheets of heavy-duty aluminum foil, about 12-14 inches wide. Place an even portion of the chicken and veggies in the center of each sheet.
  6. Fold the foil over and crimp the edges tightly to seal, leaving a little space inside for steam to circulate.
  7. Place foil packs on the preheated grill grates or on a baking sheet if using the oven.
  8. Cook for about 20-25 minutes, flipping halfway through. The chicken should reach an internal temperature of 165°F (74°C), and the veggies should be tender but still have a little bite.
  9. Carefully open one pack (watch out for steam!) and check for doneness. If needed, reseal and cook a few minutes longer.
  10. Serve garnished with chopped fresh cilantro and extra lime wedges. Serve with warm flour or corn tortillas.

Notes

Use double-layered foil to prevent leaks. Slice chicken and veggies uniformly for even cooking. Use a meat thermometer to ensure chicken reaches 165°F. For extra charred flavor, open packs during last 3 minutes and place directly on grill grates. Leftovers can be refrigerated up to 3 days or frozen up to 2 months. Reheat in oven at 350°F for 10-15 minutes.
