Microwave Mexican Cube Steaks Recipe - Beef Entree Recipes Cube steaks are round steaks that the butcher has run through a tenderizer or cube steak machine. Sometimes these steaks are made of bits of less tender meat mixed together and run through the machine. To make sure you're getting the best quality, and what you paid for, you can buy a round steak and ask the butcher to send it through the machine, or pound the steak yourself using a meat mallet. in Public bookmarkswith beeforporkmicrowaverecipes
