Buy cubed steaks, or round steaks and have the butcher cube them.
Dip steaks in seasoned flour recipe (see below). Then brown in oil. When all steaks are fried put them back in the pan they were browned in and pour mushroom soup over the top. Simmer for at least 30 minutes.
“My mom made Swiss steaks with a tomato sauce. VeLoy wasn’t fond of the tomato sauce part of the recipe so we substituted mushroom soup.”
