4 German style bratwurst
1 large white onion, thinly sliced (you can use a Madoline)
1-tablespoon olive oil
2 tablespoons stoneground mustard
Heat a pan to medium high heat on your stove top
Grease the pan with a little olive oil (enough to thinly coat the pan)
Sear the bratwurst on all sides and allow cooking for 7-9 minutes (you can release some of the juice from the bratwurst by slight incisions to the skin of the brat)
Set the bratwurst aside, and add your thinly sliced onions to the pan with the remainder of the olive oil
Allow to cook down until caramelized.
Place the bratwurst on a place and cover with the caramelized onions
Serve with the stone ground mustard.
