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.
Crumble or chop the bacon and sprinkle over the salad.
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.
