Creating these Grilled Chicken Fajita Foil Packets is a breeze. Follow these steps for a perfect result:

1. Prepare the Chicken: Slice the boneless chicken breasts into thin strips to ensure even cooking.
2. Mix Ingredients: In a large bowl, combine the chicken strips, sliced bell peppers, and onions.
3. Add Seasonings: Drizzle the olive oil over the mixture and sprinkle the fajita seasoning, garlic powder, onion powder, salt, and pepper. Toss everything until thoroughly combined.
4. Prepare the Foil: Tear off large sheets of aluminum foil (about 12×12 inches). Lay each sheet flat on a clean surface.
5. Create the Packets: Divide the chicken and vegetable mixture evenly among the sheets. Fold the foil over the filling, then crimp the edges tightly to seal each packet.
6. Preheat the Grill: Heat your grill to medium-high heat while allowing the packets to rest and marinate.
7. Grill the Packets: Place the foil packets on the grill. Cook for 15-20 minutes, flipping halfway through for even cooking. The chicken is done when it reaches an internal temperature of 165°F (75°C).
8. Remove and Unwrap: Carefully open the packets, allowing steam to escape. Be cautious as the contents will be hot.
9. Serve and Enjoy: Serve the fajitas directly from the foil or transfer to a plate. Top with optional garnishes like lime juice, fresh cilantro, guacamole, or salsa.

These easy steps will guide you in crafting perfect Grilled Chicken Fajita Foil Packets that are sure to impress.
