This recipe uses round steak which is economical but a bit tough. The long cooking time in the Crock Pot helps to soften the meat up until it is fork tender. If you wanted you could add carrots and onions, but I just did potatoes with this one. I found the idea for this recipe on a Crock Pot blog, but I didn't have all the right ingredients, so I changed it up for what I did have. This is really good, and so simple to prepare, you can have Sunday dinner in the middle of the week!
