In a large bowl, mix rice, eggs, cottage cheese, mushrooms, onion, chopped tomatoes, 1 cup of the grated cheese, Parmesan, bacon, and corn.
Grease a 13"x9" glass casserole and spread mixture evenly in the dish. Place tomato slices over top and sprinkle with the rest of the cheese, salt and pepper.
Bake at 400°F for about 40-50 minutes or until everything is well cooked and the cheese turns slightly golden.
