1 medium onion, sliced – For sweetness and depth.
2 tablespoons olive oil – For richness and to help the spices adhere.

1 teaspoon garlic powder – For savory depth.
1 teaspoon cumin – For earthy warmth.

Step-by-Step Instructions

Step 1: Preheat the Heat Source

Preheat your grill or oven to 400°F (200°C).

Pro Tip: A hot grill or oven ensures the chicken cooks through and the vegetables char slightly.

Step 2: Combine Ingredients

In a large bowl, combine the sliced chicken, bell peppers, and onion.

Pro Tip: Slice the chicken and vegetables into uniform pieces so they cook evenly.

Step 3: Season the Mix

Drizzle the mixture with olive oil and fresh lime juice. Add the chili powder, paprika, garlic powder, cumin, salt, and black pepper. Toss until everything is evenly coated.

Pro Tip: Toss well to ensure the spices are evenly distributed.

Step 4: Divide

Divide the seasoned mixture evenly among 4 large sheets of heavy-duty aluminum foil.

Pro Tip: Use heavy-duty foil—it’s stronger and less likely to tear.

Step 5: Seal the Foil

Fold the foil tightly into sealed packets by bringing the long edges together, folding them over twice, and tightly crimping the ends.

Pro Tip: Seal tightly! You don’t want any steam or juices to escape.

Step 6: Cook

Grill or bake for 20–25 minutes, until the chicken is fully cooked and the vegetables are tender.

Pro Tip: Check the chicken for doneness—it should reach 165°F internally.

Step 7: Serve

Carefully open the packets, garnish with chopped cilantro if desired, and serve immediately with warm tortillas.

Pro Tip: Watch for steam when opening the packets!
