These rolls can be filled with any ingredients you choose. I often use hummus instead of a cream cheese spread—or I make them with egg salad—or cheese with salami or ham. Roasted peppers, grated carrots, and chopped olives go well with hummus—and mayonnaise (or any other spread) will keep the rolls together. My friends have requested these rolls for years and they are easy to transport. They always make a satisfying and filling appetizer.
