Mix all ingredients together in a large bowl with your hands.
Use a spring-loaded scoop to get a consistent size meatball. Then, form them into balls using your hands.
Place meatballs on the cookie sheet lined with parchment paper.
Bake at 400° for about 25 minutes or until internal temperature is 165° when checked with athermometer.
Let cool and flash freeze on a clean baking sheet overnight.Freezing them already cooked will help you timewise for those busy days! I put them in dinner-size portions in vacuum seal bags so they will last a year.
Notes
***Read the packaging to ensure you have gluten free oats if you want a gluten free meatball.This made 48, 2 inch meatballs about the size of a clementine. You could totally make them smaller sized meatballs for littles. You can bulk these up with veggies so the meat and veggies are equal in the ball especially if you are trying to sneak in some extra veggies.The Cross Legacy provides estimated nutrition information for convenience and as a courtesy only.
