These Sweet and Sour Crockpot Meatballs are made easily with frozen meatballs and cooked low and slow in a mouthwatering sweet and savory sauce! Perfect for parties, game day tailgating, or a fun dinner! This is one of my Appetizer recipes I know you’ll want to keep on hand! Pin this recipe for later! Party foods are some of my all-time favorites! There’s something so tantalizing about a spicy buffalo chicken dip, a big platter of nachos, or a perfectly pop-able bite sized meatball....
