I would keep it simple. No veggies that require cooking and need to be served hot. Raw veggies would be the way to go. Carrot sticks, celery, pepper strips, zucchini etc. etc. Cookies, brownies and/or cupcakes for dessert and you're done. I didn't look at your recipe for the ziti, but I never put meat in mine. If you do, I would follow the other suggestion about leaving some meat free. Bless your daughter and the entire group. And have fun and enjoy the meal.
