Creating Baked Italian Chicken and Veggie Foil Packets is straightforward, and you can follow these simple steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Prep Chicken: In a large bowl, combine the chicken breasts, olive oil, Italian seasoning, garlic powder, salt, and pepper. Toss to coat the chicken evenly.
3. Prepare Vegetables: In another bowl, mix the sliced bell peppers, zucchini, and cherry tomatoes with a pinch of salt and pepper.
4. Create Foil Packets: Cut four large sheets of aluminum foil. Place one chicken breast in the center of each sheet, then top it with the vegetable mixture.
5. Seal Packets: Fold the sides of the foil over the chicken and vegetables, rolling the edges tightly to seal them. Ensure that the packets are well-sealed to avoid leaks during cooking.
6. Bake: Place the foil packets on a baking sheet and bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and the veggies are tender.
7. Check for Doneness: Carefully open one packet to ensure the chicken is done. The internal temperature should be at least 165°F (75°C).
8. Serve: Remove from the oven and let rest for a couple of minutes before carefully opening the packets. Be cautious of the steam!
9. Garnish: If desired, sprinkle fresh basil over the top before serving.
