I pat the lettuce until it's dry and squeeze the cukes, tomatoes and olives in paper towels until they are dry. I mix the veggies & torn lettuce in a bowl and put in a very small amount of Italian dressing, not enough to soak the wrap. Don't use mayo or mustard in the meat roll up and make sure any veggies you add are dry. If you make the roll ups about an hour before you go they shouldn't be soggy or wet. Chicken salad can be used but I do the whole veggie wrap (cut it in half) and add a lettuce leaf to hold the chicken salad in the wrap. Using celery instead of grapes helps make the Chicken salad drier. Chicken salad seems to fall out of a pin wheel to easily.
