I remember a green chili recipe that you brown up some chunks of pork, then make a roux with the pork grease & flour. Then stir in water & green chilies to make up a gravy, & add the pork chunks back in the stew for awhile, seasoning salt & pepper, tinker with it as you like. I can't give you anything exact & don't think I have it written down (it may be in a Tex-Mex cookbook - QG will know the one) -- but that's the jist of the recipe. I think I saw the Frugal Gourmet do something like that once on TV, and I just remembered (generally) what he did.
