1 teaspoon dry mustard
Salad
1/2 red onion, sliced thinly
1/2 lb fresh mushrooms, sliced
1/2 - 1 lb swiss cheese, grated
1 lb bacon, cooked and crumbled

Note for Dressing: This makes a lot, I usually only use about half.
Mix the dressing ingredients together and refrigerate overnight. Very important!
Toss salad ingredients together and mix in dressing just before serving.
