Meatballs and Pan Sauce
In a small bowl, mix meat and remaining ingredients together until combined. Gently, roll into 2" balls. Fry on medium heat, until brown on all sides and firm to touch. Remove from pan saving pan juices. Add one 14.5 ounce can of crushed tomatoes or 1 cup of your favorite tomato sauce. Salt and pepper to taste.
Bring to simmer scraping the browned bit into the sauce, about 15 minutes. Remove rolls from the oven. Slice and add one or two meatballs. Top with pan sauce. Serve with parmesan cheese if desired.
