I am building a menu for a third birthday party (approx 25 people / buffet dinner / November timeframe). I am looking for foods that are either (1) shaped like a triangle (when folded/cut) or (2) have some sort of "three" element to them such as three layers or three types of chocolate. I was thinking of a crepe assortment (they fold up so beautifully), but ideally, I'd want dishes that can be prepared in advance. Thanks in advance for your help!!
