Start with a well seasoned dutch oven.  Line a dutch oven with foil, if you like, for easy cleaning.

Brown 1 lb hamburger meat .  You can do this ahead of time.  Add one onion, chopped or finely diced. Drain the excess oil to one side - stack meat on top side and absorb oil with a clean paper towel.
Add:

• 2 cans Pork-n-Beans
• 2 cans Pinto beans
• 1 can Rotel tomatoes
• 1 small can tomato sauce
• 1 link Hillshire Farm smoked sausage (sliced in bite size portions).

Simmer in Dutch oven with lid on and 9  coals on top and 15 on bottom.   Simmer until all is warm through.

Enjoy,
