Sauté onion and jalapeño in the butter till softer but not too soft. Mix the soups into the pan with 1-1/2 cups of the cheese. Heat till cheese melts. In the meantime boil your noodles until desired tenderness [according to the package). I bake my chicken in advance so I don't burn my fingers while de-boning it. Mix it altogether and put the rest of the cheese on top with the cracker crumbs and bake it in a preheated oven at 350° for 45 minutes.
