Preheat oven to 350 degrees F. Lightly grease a 3-quart rectangular baking dish; set aside.
In a large bowl stir together thawed vegetables, cooked rice, beans, roasted peppers, corn, and chile peppers. Stir in 1 cup of the cheese and the broth. Transfer mixture to the prepared baking dish. Sprinkle with the remaining 1 cup cheese.
In a small bowl combine bread crumbs and melted butter. Sprinkle over vegetable mixture.
Bake, uncovered, for 35 to 40 minutes or until mixture is heated through and crumbs are golden. Let stand for 10 minutes before serving.
