In a large pan, add olive oil over medium-high heat then add in the diced smoky bacon, frequently stirring and cooking until crispy. Remove from pan and drain on a paper towel-lined plate. Reserve Bacon for later.

Keep the bacon drippings and add in the diced onions, all of the peppers, and minced garlic, sautéeing until onions are translucent.

Add the drained beans to the sautéed veggies, along with the BBQ sauce, brown sugar, mustard, salt, pepper, and liquid smoke, and half of the crispy bacon, mixing well. 

Turn the heat down to low and continue to cook, stirring occasionally, for at least 1 hour, but best if it can be simmered for 2 - 3 hours for incredible flavor.

Garnish with the remaining crispy bacon at the end, serve and enjoy!
