Chop 1/4 of a small yellow onion and mince one clove of garlic. Heat 1 TBSP of olive oil in a saute pan and add the onion and garlic. While that cooks, chop up 2 red peppers into inch long pieces. Add to the onions and garlic when they are tender. Add salt and pepper. Add 3 TBSP of barbecue sauce and 1 TBSP of mustard. Toss in bratwurst and let cook for a while until bratwurst is done and peppers are tender. Add a few handfuls of frozen or fresh green beans, 1/2 cup of water, stir and let cook until tender.
