Ingredients:

2 large sweet yellow onions  (I prefer Vidalia), diced into large squares: approx. 1/4 - 1/2"

5 lbs.  ground beef, can be replaced with turkey or venison

2 lbs.  bacon (I prefer Oscar Mayer's)

Then, there's the Beans ...  There's no prescribed ratio, or dictated types, but I typically use:

1 super-sized can of dark red kidney beans

1 super-sized can of black beans

1 super-sized can of baked beans (I like  Bushes "Homestyle Baked Beans")

1 can (white) butter beans

1 can of Great White or Northern Beans (also called Cannelloni)

1 can light red kidney beans

1 can pinto beans

1 can pink beans         

 And finally, the Sauce ...

1 cup granulated sugar

2 cups light brown sugar

2 cups BBQ sauce (Jack Daniel's hickory version, KC Masterpiece Original both work well)

1 1/2 cups ketchup

3/4 cups mustard

1/4 cup Franks hot sauce

1/4 cup dark molasses

3 or 4 shakes of Worcestershire sauce

 Add to taste, the following spices:

chili powder (I use several types:  ancho, chipotle, cayenne, and "regular" chili powders)

garlic powder

salt & pepper
