In addition to tomatillos or in my case green tomatoes, Nate suggested this basic recipe: Add a green bell pepper, a poblano, a jalapeno, 4 cloves of garlic, and an onion to the mix, wash/peel every thing and put it all in the oven on a foil lined plan (i cut everything in halves or quarters). Blacken until the skin is basically coming off the peppers. Remove, skin the peppers, combine in a food processor, blend, and then transfer to a pot. Separately cube 1-1/2 lbs of pork, mix with salt/pepper and then dust with flour. Heat a pan w/ olive oil and brown pork on all sides. Combine with veggies and simmer for a few hours. Add chicken stock to desired thick/thinness. I make it like a stew and serve over rice but it'd make a mean taco or burrito filling or on nachos or basically whatever.
