Preheat oven to 350°F. Spray casserole pan with olive oil and place in oven while preheating.
In a large bowl, mix all ingredients with your hands. Shape into 30 meatballs, approximately 1" across.
Cook meatballs for 15 minutes, flip, then cook for 5 more minutes or until crispy on the outside. Cut one in half to make sure the inside is cooked through. Enjoy!
