Step 1: Preheat your oven to 375°F (190°C) or prep your grill for medium heat.
Step 2: If using Ready Rice, follow the package instructions to heat it. For cooked rice, ensure it’s warm and ready to go.
Step 3: In a mixing bowl, combine the condensed cream of mushroom soup, water, sliced mushrooms, and frozen peas. Mix well until everything is coated.
Step 4: Take the chicken breast and cut it into bite-sized pieces for even cooking and better flavor infusion.
Step 5: Cut large pieces of aluminum foil (about 12 inches long). In the center of each piece, place a portion of cooked rice, followed by the chicken pieces, then pour the mushroom mixture over the top.
Step 6: Fold the aluminum foil over the ingredients and crimp the edges to create a sealed packet with some space inside for steam to circulate.
Step 7: Place the foil packets on a baking sheet and bake in the oven for about 25-30 minutes or grill for 20-25 minutes until the chicken is cooked through.
Step 8: Carefully unwrap the packets (watch out for steam!), and serve immediately. Garnish with fresh herbs or a squeeze of lemon if desired.
