Preheat oven to 400F. Place tortilla on a large sheet of aluminum foil. Spread 2 Tablespoons of pesto on a tortilla. Arrange 10 pepperoni slices on one half of the tortilla, followed by tomatoes, bell pepper, and olives. Sprinkle the entire tortilla with 1/4 cup cheese. Begin rolling the tortilla from the pepperoni side -- it's much easier to roll when everything is on one side of the tortilla. Roll tightly. Wrap in aluminum foil and set aside. Repeat with the remaining tortillas. Place roll-ups in the oven and cook for 15 minutes. Cheese will be melted. Remove from oven. Carefully open foil to cool completely, then re-wrap and place in refrigerator overnight to firm up. Unwrap roll-ups, and cut into 8 slices with a sharp knife. Insert one toothpick into each slice.
