This is a delicious filling that is put onto hamburger (or hot dog) rolls and baked in the oven. Fantastic for a cold weekend day when the kids need a good lunch. This recipe came from my mother. It has been one of my favorite recipes for over 30 years.
Step: 1
Preheat oven to 400 degrees F (200 degrees C).
Step: 2
Cook and stir ground beef in a large skillet until well browned, about 10 minutes; drain fat. Place cooked beef in a large bowl. Stir in tomato sauce, onion, black olives, pimentos, mushrooms, Cheddar cheese, chili powder, salt, and black pepper.
Step: 3
Spoon sandwich filling on hamburger bun bottoms, spreading to the edges. Filling should be approximately 1/2" thick in the center of the sandwich.
Step: 4
Bake in the preheated oven until the edges start to bubble, 5-10 minutes. Turn oven to Broil and continue to cook until heated through, about 3 minutes.
