In a large saucepan add onions, garlic, smokies and grape jelly. Stir until mixed well. Cook for about 7 minutes stir frequently.

Add chili sauce and mix well. Reduce heat to low and let cook for 30 minutes, stirring frequently, or until sauce has thickened.

This can also be done in a crockpot. Mix all ingredients together and cook on high for 2 hours or low for 4 hours.
