Preheat oven to 400F. Spray a large cookie sheet with cooking spray.

Mix together onion, bread crumbs, garlic, egg, cheese, ketchup, salt, pepper, and parsley in a large mixing bowl.

Add in ground beef and mix gently until combined. Do not overwork. Form into 1-inch balls and place on prepared cookie sheet.

Bake in preheated oven for 15-20 minutes, or until meatballs are browned and cooked through.
