I was inspired recently by this post on Big Girls, Small Kitchen about grilled cheese and mushroom melts. I have been playing around with variations on the theme this week. I brought in elements from a favorite salad at Prohibition Bar-- namely frisee, which goes lovely with mushrooms, and of course, bacon. This is a fall sandwich of no regrets. You're burning off extra calories just by staying warm, so I promise there's no harm.
Take come of your bacon grease and saute' mushrooms in it, with a bit of garlic.
Place sliced havarti on wheat bread, and pile all elements together.
