This is my wife's special meatball recipe ... listen very carefully, I will say this only once ...
Mix together a finely-chopped onion, ground beef or turkey, a teaspoon each of garlic salt, chili powder, Italian seasoning, steak seasoning, and a good tablespoon of cumin. Add an egg, and enough breadcrumbs to mix to a moist but workable consistency.
Form into balls and fry in a little olive oil. When the meatballs are browned, add some tomato pasta sauce and leave to simmer.
Meanwhile bring a pan of salted water up to the boil and cook the pasta. Drain, and serve with the meatballs.
This same mixture also makes amazing burgers, if we ever get a summer this year :(
