A versatile stew base that can be switched to suit any palate. The tomatillos give this stew base a plenty of citrus flavors, so feel free to leave out the additional lime juice. The roasted poblanos provide a very subtle heat that is not at all overpowering. If more heat is desired, add a couple of chopped chipotles in adobo or 2-3 chopped serrano or jalapeño chiles. Serving Ideas: When the stew has cooked about halfway (step 4), add meat of choice: shredded roast chicken or thinly sliced boneless pork chops would be equally good. In the original version, I used 1 1/2 pounds of pre-cooked beef tongue; the richness of the meat paired quite well with the tart flavors in the stew. For a veggie version, stir in some cubed eggplant or winter squash or whatever protein substitute you like.
