Is this a trick question???
My personal favorite is a Mexican Fattie
Ground Beef w/ mexican cheese blend, avocado, tomatoes, red onion, salsa, four seasons italian dressing and little fire roasted habenro sauce for heat.
Yes -use the venison sausage. I have done it in the past with no problems. My filler was bacon, swiss cheese, mushrooms, and a sauce that included Peter Luger Sauce (steak sauce from a place in Brooklyn, NY), teryaki sauce, and worshtishere and some chopped garlic. It held together great with the bacon weave.
