Nope, sorry! It’s tempting to buy stew meat because it comes packaged already cut up into neat little cubes, but it’s just too tough for this recipe. If you really want to use stew meat for this Easy Mexican Beef Tips recipe because dang they are reasonably priced, I feel you. If you want to use them, I would recommend hitting the stew meat with the marinade, then slow cooking until tender. Once tender, simply add the stew meat to the tomato sauce goodness and serve.
