In a frying pan over medium heat, add the oil and saute the onion, chillies, red pepper and garlic. Fry for 3 minutes. Add the vinegar and beans.
Turn down to a low heat (if too dry, add a splash of water) and add the rest of the ingredients. Cover and leave for 10 minutes - check and stir regularly adding a little water if required.
After about 10-12 minutes turn off heat and mash beans with a potato masher/fork for a rough texture or use a hand blender for a smoother texture.
Serve alongside a chilli con carne or with tortilla chips .Recipe courtesy of Tabasco®
