im just riffing here
A galette if you have a bakery you trust. Peach or blueberry I think. the right balance between delicious, effortless, and easy to eat
blood oranges or pears and dark chocolate (tho this is a little wintry I guess)
heirloom tomatoes sliced salted and plated with olive oil
hunks of delicious bread with slabs of cheese and a bowl of cornichons
alternatively potato chips and caviar
good luck & congrats in advance!
