A great presentation that lends itself to endless variations. My father served these simple make-ahead appies at cocktail parties, along with a can of Spanish peanuts and a bowl of mini-pretzels on the side. Tip: Depending on your theme, for Hawaiian try a studded pineapple (instead of grapefruit) and a jar of macadamias in place of the peanuts-- be as creative as you want! Great for the cocktail hour, luaus, or anytime! Thanks Dad!!
