Cut the top off of three rolls. Hollow out to form a personal dip bowl. Cut the remaining 3 rolls into 6 slices each.
Place these, plus the tops from the first 3 rolls, on a baking sheet. Brush both sides lightly with olive oil. Toast both sides under the broiler until lightly browned.
In a saucepan, combine cream cheese, sour cream, hot sauce and cheeses.
Stir until heated through. Fill each dip bowl with hot dip and serve with the toasted roll slices and celery.
