Slow Cooker Cube Steak

"These Slow Cooker Cube Steaks are slow-cooked with sweet onions and a perfect blend of dried herbs in a savory beef broth and French onion soup base that thickens into a tasty gravy. For the ultimate meal, serve over mashed potatoes with a side of sautéed green beans or honey-roasted carrots. It is beef steak, usually top round or top sirloin, that has been flattened and tenderized by beating with a meat mallet or a mechanical tenderizer. This process creates what looks like little cubes on the outside of the steak, giving it its unique name. This cut of beef is often breaded and fried for chicken-fried steak. The store sells them mechanically tenderized, which I find slightly better. However, the process is done quickly at home with a cutting board, plastic wrap, and a meat mallet. "
