the ropa vieja was a huge hit...probably could've used a fattier meat but it was fine...served it with brown rice, black beans and avocado
here's what I did different - (two steaks, large onion and pepper)
15 oz can of tomato sauce and I rinsed the can with a little water and added the water (no beef broth or oil)
coated the meat with garlic powder, cumin, salt, pepper, and a little cayenne
no cilantro (because I didn't have any

)
added two peppers from a can of chipoltes in adobo sauce - sliced thin and some of the adobo sauce
probably about 1/4 of vinegar
cooked 6 hours....
I didn't pre-brown it but it would've been good if it had hit the
grill for a searing before the crock-pot
I layered the onion and peppers and steak, mixed everything else together and poured it over all
