This dish is great for parties, and is fun for kids too. They love the color and texture of the hummus, and its fun to prepare with them. Serve this dish with assorted colorful vegetables, chips or crackers, corn tortilla, cheese or walnuts. Omit horseradish as needed, substituting 1-2 teaspoons wasabi paste to taste. If traditional Balsamic is too strong, use white Balsamic, rice wine vinegar or try other vinegars like red or white by testing a smaller amount than the 2 tablespoons.
