"Delicious had great flavor but I would definitely marinated overnight"

"@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!"
