Venison Roast

3 lb chunk of venison roast
2 cup onion cut up (2 in. Pieces)
2 cup potato cut up
1 cup carrots cut up
1 cup fresh mushrooms sliced
2 tbsp liquid smoke
3 tbsp Worchestershire sauce
3 tbsp soy sauce
1/2 cup beef broth

Put a large oven cooking bag in an oblong baking pan (so that the bag fits inside the pan). To the bag, add the venison. Add all liquids, then veggies around the meat. Put the 'shrooms on top of everything else, then the spices on top of them. You want to have about 1 inch of liquid in the bottom of the bag, so if you need more, add a little water or white wine.
Seal bag. Poke several small holes in top of bag to let steam escape. Bake at 300-325 for 3-1/2 hours. (If you chop the veggies big, they won't overcook).
