This is so easy.
1 bottle chili sauce
1 cup grape jelly ( yup, grape jelly!)
1-3 lb Little Smokies sausage (cocktail sausages)
Mix all ingredients.
Cook in crockpot on medium high setting for one hour, or on stove top for 30 minutes.
(I personally like mine to cook slowly for a longer time until sauce thickens and is clinging to the sausages.).
