  • ½ teaspoon salt

  • ½ teaspoon dried oregano, crushed

  • ¼ teaspoon ground black pepper

  • 1 ½ pound lean ground beef

  • ½ cup chopped green sweet pepper (1 small)

  • 2 tablespoon packed brown sugar

  • 1 tablespoon yellow mustard

  • 1 teaspoon chili powder

  • ¼ teaspoon garlic salt

  • ¼ teaspoon ground black pepper

  • teaspoon bottled hot pepper sauce

  1. In a large bowl, stir together egg, bread crumbs, 1/3 cup onion, the salt, oregano, and 1/4 teaspoon black pepper. Add ground beef; mix well. Shape meat mixture into 32 balls. Arrange meatballs in a single layer in an ungreased 15x10x1-inch baking pan. Bake, uncovered, in a 350 degree F oven for 25 minutes. Drain off fat.

  2. For the sauce, in a 3-1/2- or 4-quart slow cooker, stir together tomato sauce, the remaining 1/3 cup onion, the sweet pepper, brown sugar, mustard, chili powder, garlic salt, 1/4 teaspoon black pepper, and the hot pepper sauce. Add cooked meatballs, stirring gently to coat with sauce.

  3. Cover and cook on low-heat setting for 3 to 4 hours or on high-heat setting for 1-1/2 to 2 hours.

  4. Place four meatballs on the bottom of each bun. Top with some of the sauce and some of the cheese. Add bun tops. Makes 8 servings.
