Preheat oven to 375°. Line a rimmed baking sheet with parchment paper. Separate the kale leaves from the stem. Chop the leaves.
In a large mixing bowl, add all of the ingredients. Using hands or a heavy spoon, mix ingredients together lightly but thoroughly. Make sure everything is well dispersed.
Using a heaping tablespoon of mixture per meatball, roll the mixture between your hands into 2 inch round meatballs. Place the meatballs close together but not touching onto the lined baking sheet.
Bake in preheated oven for 15 to 20 minutes (turning halfway through) until cooked through (165° internal temperature).
Serve as is or with your favorite tomato or marinara sauce!
