Pork Roast with Potatoes and Onions

1 (5 to 6 lb) pork roast
2 lbs onions-thick sliced
2 lbs potatoes-thick sliced
Garlic salt
cracked black pepper
Mesquite seasoning (or other smoke flavored, BBQ seasoning)
1 (12 inch) Dutch Oven
a little cooking oil

Place a well greased 12 inch Dutch Oven on top of your bottom coals. Rub spices on roast and place in Dutch Oven. Place lid on and pile on your top coals. (If you don't have camp fire coals and use regular store bought charcoal -- 8 coals on the bottom -15 on the lid top.)

Cook 2 1/2 to 3 hours (add coals as they are used up), then place sliced onions on top of roast. Add a good sprinkle of spices, then add potatoes around sides and on top roast; season again. Cook about another hour or so, then serve.
