FOOOOOD.
My mother is a genius. She just discovered the most amazing catering idea for our wedding:
A big green truck that has a brick pizza oven in it. Serving unlimited brick-oven pizzas made on-site (choose your own toppings), green salad, GELATO, and cappuccino.

Um...no words for how perfect this is.
