Subway is a favorite quick-dinner spot (for the boys), with meatball sandwiches nearly always the choice. Found this Subway just down the hill from us at the new house (next to the cheapest Arco around!) so we go there now when we're home already. If we're picking up dinner on the way home from school, we head to the one near Little School. Cory's favorite fast food is McDonald's so we trade off.
Mom's favorite fast food is no fast food, so I usually just make a sandwich for myself at home or heat up leftovers unless we're eating on the run.
