Sheboygan Brats'n Vidalia Onion

I am told that this is a Wisconsin tradition - well it's an Okanagan tradition now too. Great when you have a gang in for a game or whatever

• Ready In: 40 mins
• Serves: 4

Ingredients

• 4  bratwurst sausages (Your favorite brand)
• 1  large  vidalia onion, sliced into 1/4 slices (if vidalia onions are not available use any sweet onion, double the onion if
• 1⁄2 cup Dijon mustard
• 4  sausage  hot dog buns (large Italian)
• 1  bottle  lager or medium dark beer
• 3⁄4 cup  sliced mushroom

Directions

1. Boil the beer until it is reduced to 1/4 cup, cool.
2. Mix mustard with just enough beer to give it the consistency of ketchup.
3. Boil the brats for about 5 minute in water and prick in a couple of places, this will remove most of the fat Place brats in a large skillet with the onion& mushrooms medium heat, cover About 5 minuts later check and carefully turn the brats, onions and mushrooms Coat the onions and mushrooms thickly with the mustard mixture.
4. Continue cooking until the onions& mushrooms are tender and the brats are browned Add more mustard sauce if you wish.
