For a spicier kick, add a pinch of cayenne pepper to the meatball mixture or the sauce. Fresh pineapple can be used instead of canned. Just make sure to chop it into small, bite-sized pieces. These meatballs can be made ahead of time and frozen. Simply bake them until almost done, then freeze. When ready to serve, thaw and finish baking with the sauce. Serve these meatballs with rice, quinoa, or mashed sweet potatoes for a complete meal.
