I got this recipe from Ken, someone I worked with years ago. He brought these to a potluck we had, and I had to have the recipe. We've all had those potluck meatballs in sauce, but to this day, I still think this is the best sauce I've ever had on them. To make a meal of this, add chopped bell peppers of various colors, chopped onion, chopped carrots, and chunked pineapple to the Crock Pot as well. Serve over rice.

The sweet and sour sauce in this recipe is a real winner. It's thick, sticky, sweet, and tangy. It's delicious on the meatballs, but it would also be great on chicken. There's definitely a punchy, tangy flavor from the vinegar. As the sauce simmers in the slow cooker, it thickens, coats the meatballs, and soaks into the meat. Add peppers and onion, and serve over rice for a Crock Pot dinner. Or, add them to a bowl and serve as an appetizer.

    For the sauce, combine water and corn starch in a bowl. Whisk until smooth and corn starch dissolves.
