Flank Steak Fajitas

"Our family loves Mexican food, and this is one of our favorites," says Twila Burkholder from Middleburg, Pennsylvania. The slow cooker tenderizes the flank steak for these filling fajitas, which have just the right amount of spice.

    @ShotofJager, if your meat was tough then you did not either have enough juices in your crock pot or cook on low for a long enough period of time. I have cooked every type of meat possible in my crockpot and had the toughest of meats come out perfectly tender. I cannot wait to try out this recipe although I am going to add some onions and fresh lime juice!

    this is such a fantastic, easy recipe. the crockpot really tenderizes the meat (and the whole house smells great also)

    Great flavor! The steak was very tender and just melted in your mouth. I used a can of diced tomatoes (w/no chilies) and no peppers. We skipped the tortillas and served over bed of Romaine lettuce w/shredded cheese and sour cream. I will definitely make this again!!

    the steak fell apart at the end. there were no strips of steak to even make a fajita. The steak stayed tough, never got tender. Do do not make this crock pot recipe. I did and threw it away!
