I did it! I made this very recipe tonight! And I followed the recipe PRECISELY!
One package Kirkland brand brats. In the boiling water with beer (subbed Dos Equis) for ten minutes. Didn't want to waste the onion so I put it in with the celery rather than in the boil. Campbell's Cream of Cheddar isn't sold at the Tucson Frys (and I hate mushrooms), so I subbed two cans of GF Cream of Chicken soup and two cups of grated sharp cheddar.
Trying it a third time today. I just opened a jar of green chile yesterday, so will use that instead of jalapenos. And white wine instead of beer in the boil. Cheese blend instead of sharp cheddar.
Came out awesome! Tim Walz rocks!
