This was GOOD!
My hubby made them last night while I was at work.

Use a large skillet pan with a lid

2 to 3 cans beer (labatt blue)
4 to 6 large onions sliced in large rings (some chunks too)
6 original Johnsonville Brats

Pour in Beer, add onions start to simmer add brats on top. Cover and simmer, Stir every now and again. Let brats get covered with the onions.
He cooked this way about 45 min.
Then he fired up the grill and put his and my brothers on to grill for about 5 min. I choose NOT to have mine grilled -- no need in my opinion.

serve on buns with cooked onions, mustard & ketchup.

VERY GOOD! The onions almost carmelized in the beer.

I like stout ketchup & used that on mine .... to make:
just mix gineuss (Irish stout beer) & ketchup, store in fridge.
