Spicy Italian Meatballs

Preheat oven to 350°F. In a large bowl combine egg, bread crumbs, 1/4 cup onion, pepperoncini peppers, Italian seasoning, and the 1 clove garlic; mix well. Add ground beef and sausage; mix gently until combined. Shape mixture into twenty-four 2-inch meatballs. Place meatballs in a 15x10x1-inch baking pan. Bake for 30 minutes; drain well.

Meanwhile, in a 4- to 5-quart slow cooker combine crushed tomatoes, 1/2 cup onion, the vinegar, 2 cloves garlic, oregano, and crushed red pepper. Add baked meatballs to slow cooker; stir gently to coat.

Cover and cook on low-heat setting for 4 to 6 hours or on high-heat setting for 2 to 3 hours. Skim fat from sauce before serving.
