Chiles en nogada
My favorite. Don't read the description if you're hungry. From Wikipedia: Chiles en nogada is a dish from Mexican cuisine. The name comes from the Spanish word for the walnut tree, nogal. It consists of poblano chiles filled with picadillo (a mixture usually containing chopped or ground meat, aromatics, fruits, and spices) topped with a walnut-based cream sauce and pomegranate seeds, giving it the three colors of the Mexican flag: green for the chili, white for the nut sauce and red for the pomegranate.
