If you are choosing to use bacon, cut slices in the chunks. Set you Instant Pot to saute and cook for 7-8 minutes, until done.
Use the bacon grease to saute your onions, peppers and garlic for 5 minutes. NOTE- If you are NOT using bacon add 2 tbsp oil to Instant Pot for the saute method.
Next add in your beans, light drained, and tomatoes.
Add in your broth to the fill line and stir in BBQ Sauce, Worcestershire, and chili powder.
Place lid on Instant Pot, and cook at high pressure for 12 minutes
Once cooking is complete, quick vent your Instant Pot, and use a hand held blender or potato masher for a smoother texture.
Garnish with sour cream, cheddar cheese and cilantro (optional)
