Layer the sandwich meat slices and roll up like a cigar. Slice with a knife. Add to the lettuce. Note: If your meats are too thick to roll up, just slice them into bite-sized pieces instead.
Cut or chop the pepperoni into bite-sized pieces. If using the smaller pizza-sized pepperoni just quarter the slices.
Slice the cheese and add to the lettuce along with the tomato and onion.
Sprinkle with salt and pepper to taste.
Serve with your favorite dressing.
Notes
This salad can be made a day ahead. Just cover and store in the fridge.
