In a small bowl, stir together cream cheese, dried pineapple, pineapple preserves, and Dijon mustard.
Spread 3 tablespoons cream cheese mixture onto each tortilla. Place 3 ham slices over cream cheese layer on each tortilla. Top ham layer with an even layer of arugula or spinach.
Roll up tortillas tightly. Wrap each tortilla in plastic wrap, and refrigerate for at least an hour and up to a day.
Just before serving, unwrap tortillas and place on a cutting surface. Using a serrated knife in a gentle sawing motion, trim and discard ends from each tortilla. Cut each tortilla into 8 slices.
Just before serving, garnish slices with a dollop of pineapple preserves, if desired.
