Wash the lettuce and tomatoes. You can use iceberg lettuce or a good romaine lettuce. The crunchier the lettuce, the better.
Slice the tomato and onion into thin slices.
Lay the lettuce leaves out onto a piece of parchment paper, staggered or fanned out with half of each leaf on top of the leaf underneath.
Add 2 slices of provolone cheese down the middle.
Spread the mayo, along with the Italian dressing, over the cheese.
Add onion and tomato slices.
Shred the cheddar cheese on top of the tomatoes.
Then add the roast beef.
Finally, wrap up your lettuce wrap, using the parchment paper to help hold it all together. You can even tie a string around it to hold it in place.
And that's it! It's ready to serve and enjoy.
