My mother made these for us four girls. Money was tight and she couldn't afford steak very often. These use ground beef. I use a 80/20 lean to fat. You can use ground round but it tends to be a little too dry. This is great with mashed potatoes. Everyone I have ever made it for loved it. The first time my DH had it he never knew it was ground beef. He just commented on the tenderness of the steak!
