Looking for a super easy supper idea? Look no further than Crockpot Cube Steak and Gravy. With a pound of cube steak, an envelope of onion soup mix, and 2 cans of cream of mushroom soup (or the equivalent of Cream of Something Soup mix), you can put a delicious home cooked meal on the table with almost no effort. We like this dish over mashed potatoes, but if you are really in a hurry, serve it over instant rice with a salad on the side. Slow cooking the steak all day makes the meat incredibly tender and the onion soup mix seasons the gravy perfectly.
