Drain all but 1 tablespoon of bacon grease from the skillet. Add 1 tablespoon olive oil and when hot add the diced onion, red pepper and jalapeno. Season with salt and pepper, saute for 5-8 minutes or until soft. Add the black beans and cook 1-3 minutes or until warmed through. Remove from the heat and, using a spatula, place the mixture onto a plate.
