Add chili sauce, grape jelly, Worcestshire sauce, & pepper to cold crockpot.
Whisk mixture until smooth.
Pour in frozen meatballs and gently stir until all meatballs are coated in sauce.
Turn crockpot on low for 6-7 hours or high for 3-4 hours. (We prefer the low heat longer cooking option!) Be sure to stir meatballs occasionally, if possible.
Serve with toothpicks and watch them disappear!
