If you happen to find yourself with one 28-ounce can of tomato puree and one 15-ounce can of tomato sauce instead of what the recipe calls for above, let me tell you that you'll be completely fine!
You can also brown the meatballs in a skillet in vegetable oil (instead of baking).
I used extra lean ground turkey for this recipe because that's what I had on hand; however, you can use regular lean turkey which has a little more fat content and would be my first choice recommendation.
