Romano or Parmesan cheese (if using an entire head of lettuce, use entire container of good quality cheese in dressing. If using 1/2 head lettuce, use 1/2 container of cheese.)
Salt & pepper (to taste) but allow that cheese and bacon will add saltiness to the salad.
Optional ingredients: hard boiled egg, green onions, fresh spinach, broccoli etc... Perhaps some sunflower seeds or pine nuts.
For a main dish add layers of cooked chicken, turkey, pancetta etc...
Arrange in serving bowl, lettuce, red onion, cauliflower, peas and any other choices in layers.
Mix mayonnaise and cheese together, spread over top of salad, cover and place in refrigerator.
Cook bacon, chop and set aside to top salad before tossing.
