Preheat oven to 400˚F. Spray the foil sheets with cooking spray and set aside.
Prepare the Fajitas Seasoning Mix.
Combine rice, water, and 1 tablespoons fajitas seasoning mix in a bowl; stir until well incorporated. Using a slotted spoon, divide the rice mixture evenly over each foil sheet.
Season the chicken breasts with salt, pepper, and rub with some of the fajitas seasoning mix. Place the chicken breasts over the rice.
Arrange the peppers and onions on the sides of each chicken breast. Drizzle olive oil over all the ingredients.
Combine the shredded cheeses and divide the cheese mixture evenly over each chicken breast.
Fold the sides of the foil over the chicken, covering it completely, and seal the packets closed. Transfer the foil packets to a large baking sheet.
Bake for 30 to 33 minutes or until the chicken's internal temperature registers at 165˚F.
Remove from the oven and carefully open up the foils away from your face. Put the packets under the broiler for 3 to 4 minutes, or until browned.
Remove from the broiler and squeeze lime juice over the food.
Garnish with sliced avocados, sour cream, and cilantro, and serve.
Cooking Chicken: Make sure not to overcook the chicken. Using a meat thermometer will ensure your chicken reaches the ideal internal temperature of 165°F.
Make It Your Own: You can easily customize this recipe by adding other favorite fajita ingredients, such as black beans or corn.
Rice: For this recipe, please use quick-cooking Minute Rice. Any other rice should be cooked before adding it to the foils.
Fajita Seasoning Mix: If you don't want to make your own, use store-bought fajita mix or taco seasoning.
Grill the foil packets on a preheated grill for about 25 minutes, or until done.
Foils: Use heavy-duty foils and ensure your foil is sealed tightly to prevent steam from escaping.
