Place egg on top of steak and roll steak like a jelly roll.( you could also chop egg but we liked the look of whole egg when sliced when we were younger).
Tie securely with string.
Brown steak on all sides - add to favorite spaghetti sauce.
Cook over slow simmer until tender -- several hours.
Remove from sauce and before serving, untie string, slice 1 to 1 1/2 inch thick pieces.
Serve with your favorite pasta! Much more impressive than meatballs!
