One I really like is a Weight Watchers recipe, but me and my husband both really like it and it freezes well:
1 spray(s) cooking spray
1 cup(s) canned yellow corn, drained, or frozen, thawed corn kernels
1 Tbsp canned green chili peppers, chopped, mild or hot
15 oz canned pinto beans, rinsed and drained
1 cup(s) long grain cooked brown rice, fresh or day old
7/8 cup(s) Mexican style blend shredded cheese
3/4 cup(s) fat free sour cream (or plain greek yogurt works great too)
1/4 tsp chili powder
1/4 tsp table salt
1/8 tsp black pepper
2 Tbsp uncooked scallion(s), chopped (dark green part only)
Instructions
Preheat oven to 350ºF. Coat a 2-quart glass baking dish with cooking spray.
In a large bowl, combine corn, chilies, beans, rice, 3/4 cup of cheese, sour cream, chili powder, salt and pepper; stir in scallions.
Spoon mixture into prepared baking dish and bake for 30 minutes. Remove from oven and sprinkle with remaining 2 tablespoons of cheese. Return to oven and bake until cheese melts and casserole is slightly bubbly, about 10 minutes more. Let stand for 5 minutes to firm up before slicing into 6 pieces. Yields 1 piece per serving.
I usually use whatever other veggies I have around that could go in (like bell peppers, onions, etc) and use chili beans in sauce instead of the regular pinto beans. Double it, put it in a foil pan and it freezes great!
