Basic Meatballs

In a large bowl, whisk egg. Add ground beef, bread crumbs, onion, milk, Worcestershire sauce, salt and pepper. Mix until combined. Gently shape mixture into 1 1/2 inch meatballs. Heat oil in a large skillet over medium-high heat. When hot, but not smoking, add meatballs (do not crowd) and cook until browned and thoroughly cooked, about 15 to 18 minutes. Adjust heat as needed. Drain on paper towels. Add to spaghetti sauce or serve as an appetizer with desired sauce.
