Notes from the Test Kitchen:
Surprise your guests with these magnificent meatballs. The chili sauce and pineapple turn into a wonderful sauce. We're definitely serving these bite-sized goodies at our next party.
Mix all ingredients, except meatballs, in a large crock pot. Add frozen meatballs and stir to coat them with sauce. Cook on low for about five hours, carefully stir occasionally. The sauce will caramelize as it cooks.
