Preheat oven to 325 F.

Heat a large skillet over medium-high heat.

Add the bacon and cook, stirring constantly, until the bacon starts to crisp.

Use a slotted spoon to remove the bacon to a paper towel-lined plate to drain. Do not remove any fat in the skillet.

Add the bell pepper and onion to the skillet and cook until softened, stirring often, 5-6 minutes.

Place all ingredients into a very large bowl and stir to combine well.

Spray a 9" x 13" baking dish with non-stick spray. Pour in the bean mixture and spread out evenly.

Bake for 1 hour or until bubbly hot. Note: If your pan is full to the brim, you might want to place a large baking dish on the oven rack below to catch any drippings that might flow over the side.

Let cool slightly before serving.
