Veggie roll-ups

My mom made these for a get-together recently while I was visiting, and they disappeared pretty quickly. Fairly simple to make, they do take a bit of planning and chopping.

1 package of cream cheese, at room temperature
2 tbsp mayonnaise
3 cups finely chopped vegetables (she used red, green and yellow peppers, broccoli, green onions, olives and mushrooms, but you could use anything, really)
15 large tortillas

Mix cream cheese with mayonnaise. Cut sides off tortillas to make them more square, then spread with a medium-thin layer of cheese mixture. Spread a layer of vegetables on top, then roll up tightly. Wrap in saran wrap and refrigerate at least 2 hours. Unwrap saran and slice into 3/4 inch pieces. Mom used whole wheat tortillas and tomato ones, and arranged them alternately on a plate. Make sure the veggies aren't too big, and I wouldn't use anything too juicy (like tomatoes).
