Marinade: ½ cup lime juice, ¼ cup tarragon vinegar, ½ cup olive oil, 1-2 cloves roasted garlic, minced; 2 finely chopped jalopeno peppers. Marinate chicken breasts (or beef steaks) in marinade at least 2 hours or overnight, turning occasionally. Grill over hot coals until done. Slice into thin strips. Set aside. In a medium sauce pan, saute 1 finely chopped onion in a little oil until soft. Stir in 1 can cream of mushroom soup, ¼ cup sour cream, 1 can diced green chilies, 2 tsp cumin, ½ tsp turmeric and ½ cup shredded Monterey Jack cheese. Reserve 3/4 cup of this sauce and set aside. Stir chicken strips into pan and heat through.
Roast 4 Poblano peppers as follows: place whole peppers over hot coals or under broiler. Roast thoroughly, rolling them around so that the skin on all sides burns and turns black. Immediately place in Dutch oven and cover with tight fitting lid. Let stand 15-20 minutes. Wearing gloves, cut off the stem end of each pepper and scrape off the burnt skin.
Fill each pepper with chicken filling. Place in casserole, drizzle with reserved sauce and heat in 350 oven 20 minutes. Sprinkle with ½ cup Jack cheese and heat until cheese melts.
Serve with refritos, guacamole and tortilla chips.
