This makes a GREAT Sunday Dinner. Not only can you make this in the oven or the crockpot, but you can make it in a Nesco Roaster. Keep the heat of the Nesco at about 200-250*F throughout cooking. Rachael's Recipe Notes: You can start this in a large skillet and then transfer the meat to a slow cooker, add the onions, seasonings and tomato sauce and let it cook on LOW for 6-8 hours. The gravy this makes tastes wonderful over mashed potatoes.
