Grab a large skillet, brown the beef, onion, and bell pepper. Drain grease, if any. Combine the noodles, meat mixture, soup, 1-3/4 cup cheese, chili sauce, pimento, salt, pepper, chili powder, garlic powder, and 1 cup water. Grease a 9 by 13-inch pan. Preheat oven to 350 degrees. Scoop the mixture into the baking dish. Sprinkle with bread crumbs and cheese. Bake uncovered for 40-45 minutes or until cooked through.
Toss bread crumbs with the melted butter. Sprinkle on casserole before baking
