Easy Enchilada Casserole
In large sauté pan, brown ground beef and onion; drain. Stir in chili pepper, jalapeño and salt; set aside. Butter bottom of 13x9" glass baking dish; arrange 6 tortillas slightly overlapping in bottom of prepared pan. Layer ground beef mixture, black beans and corn over tortillas; top with remaining tortillas. Sprinkle half of cheese over tortillas; spread tomatoes evenly over cheese. Bake in a preheated 350° oven until heated through and bubbling around edges (about 45 min.); sprinkle with remaining cheese during last 10 min. of baking.
To Serve: Cut into squares; garnish with desired toppings.
Good to Know: If you like your enchiladas hot and spicy, use more of the seeds and membrane from the jalapeño pepper. That's where the heat is!
