In a large bowl, use your hands to evenly combine the chia gel with the remaining meatball ingredients. Preheat oven to 375 F. Line a baking sheet with foil; coat lightly with baking spray. Scoop meatball mixture into 50 servings onto baking sheet. Bake 10-12 minutes; remove from oven. Cool half of the meatballs & freeze for another meal.
