This is a favorite meal of mine that is quick and healthy. You can swap out the turkey for any other ground meat (pork/beef/veal blend, chicken, etc). I use a lean ground turkey, but not the 99% fat free- that ends up way too dry.
If you mix up the ingredients, form into meatballs, and then refrigerate for about 30 minutes they will hold their shape best. I really am not too particular about that, so I usually skip that step (unless I make them earlier in the day).
You can use these for spaghetti and meatballs, or for sandwiches. We usually make a meal out of it by just serving them with a vegetable on the side, and maybe a salad. Easy, low carb, and healthy.
