I like the challenge of making traditional-esque Thanksgiving items, but making them more delicious and globally inspired. We're vegetarian now, but when we ate meat, we tried making Vietnamese-flavored turkey meatballs with a rice-based stuffing kind of dish and spicy greens and sweet potatoes sautee that was delicious. We incorporated the cranberry into dessert.
It's sort of like Iron Chef. Pick a dish for each of the traditional ingredients, but spice it up. With older kids, they each do a couple dishes in a competition to come up with the best recipe. It ends up being pretty collaborative.
