Layer Salad

Make a day ahead in a 9x13 pan

Break up 1 head of lettuce, spread over bottom of pan.  Layer crisply fried bacon, 1/2 pound crumbled.  Thinly slice cauliflower and layer over bacon.  Thinly slice purple onion and layer on top.  Sprinkle with grated cheese.  (I like to add frozen peas)

Mix 2 cups mayo with 4 Tbsp. sugar.  Spread over top.  Sprinkle with grated Parmesan cheese.  Cover tightly with plastic wrap.  Let stand overnight or at least 8 hours.  Don't stir.
