The gravy is made right in the crock pot along with the steak ... To make cube steak, start with a top round steak (or a sirloin, if you're feeling fancy or got a really good deal on these).
The beef sirloin becomes melt-in-your-mouth tender ... swimming in a savory sauce. This Crock Pot Pepper Steak is perfect served over steamed rice, egg noodles, or even mashed potatoes.
