1. In a large bowl, mix the ground beef, bread crumbs, onion, milk, egg, and the next 4 ingredients. 2. Shape the mixture into 1 inch balls. 3. In a large skillet, over medium heat, melt the shortening. When hot, add the meatballs in batches, in a single layer. Brown on all sides, and as they are done, place them on a platter on layers of paper towels to drain. 4. Remove the fat from the skillet and add the chili sauce and jelly. Over medium-low heat, stir the sauce constantly until the jelly is melted and the sauce is heated through. 5. Return the meatballs to the pan and gently stir them until coated. Simmer over low heat for 30 minutes. 6. To serve, keep them warm in a crockpot or chafing dish. Serve with toothpicks. YUM!
