Add a few slices of chicken to a large cutting board. You will want to overlap/layer them partially folded, do not lay them flat on the board.
Spoon the mayonnaise on top of the chicken. Add salt and pepper to the mayo to taste.
Slice the tomato and add to top of mayo along with the lettuce.
Layer the cheese and then the remaining chicken.
Using two large knives, chop the chicken until all ingredients are mixed and finely chopped.
Divide and scoop the mixture onto the rolls.
Notes
Use your favorite deli chicken and cheese, there are many combinations and we like to mix it up. A classic combination is buffalo chicken and sharp cheddar.
When chopping the chicken you may want to start slowly, no need to chop all the way through at first, it can be messy if trying to go too fast.
You can also add other toppings to the mixture as you see fit, we sometimes like to use pickled peppers to add a little heat depending on the type of chicken and cheese we use.
Any type of roll will work, however, a softer larger roll is recommended so that the filling does not completely squeeze out.
This does make overstuffed sandwiches and not all of the filling will fit in the roll, we like to scoop up any that has fallen out with chips.
