I just made this recipe. It is sitting on the stove as we speak and it smells and tastes so good. The recipe originally called to simmer the pork, tomato sauce, water, onions and garlic for a half an hour. This really over cooked the pork in my opinion. Especially when coupled with the second simmer so I adjusted the simmer time down. You'll want to watch it so it is down to your likeing. Next time I make this recipe I will cube rather than strip the pork (what!!! Naked Pork!!!!). I love pinto beans so that's what I used. I am sure you could use any can of beans you like.
