Sweet and Sour Meatballs: tender meatballs simmered in a tangy sweet & sour sauce. Make them in the crockpot or on the stovetop; they're easy & so delish!
Place the ground meat, bread crumbs, milk, onion, egg, salt, and pepper in a large bowl and stir together until combined.
Mist the crock pot insert with non-stick spray, roll 1-tablespoon sized balls of the mixture between your palms, and place in a single layer at the bottom of the slow-cooker.
Pour the sweet and sour sauce over the meatballs, and cook (covered) for 1 to 2 hours on high heat, or for 3 to 4 hours on low heat.
In a smaller bowl, whisk the brown sugar, vinegar, ketchup, soy sauce, crushed red pepper, and orange juice together, and pour it over the meatballs.
About 30 minutes before serving, whisk the cornstarch and water together and stir into the sauce.
Cover and continue to cook until the sauce has thickened.
Garnish with sliced scallions and sesame seeds.
