In a small bowl, mix together chia seeds & water; let stand for about 20 minutes. In a large bowl, combine remaining meatball ingredients. When chia gel is ready, add to meat mixture. Using your hands, combine ingredients well. Preheat oven to 375 F. Line a baking sheet with foil & lightly coat with baking spray. Scoop into 50 meatballs; place on baking sheet & bake 10-12 minutes. Remove from oven, cool completely if you are choosing to freeze half for a later meal. Set aside the amount you are using for this meal.
