Slice cooked chicken into strips or chunks and set aside. Cut tomatoes in half and heat up canned corn in microwave.
Slice 1/2 a green or red (or both) bell pepper and onion. Heat a small skillet over medium heat and add a little olive oil or butter. Cook the bell pepper and onion together until soft. Add the chicken if you want it reheated.
To assemble salad, add rice to a bowl and top with lettuce, cooked peppers and onions, tomatoes, and corn.
Drizzle with store-bought Chipotle Ranch dressing.
