I've taken beer. Warm is great at the take-out but it's not worth carrying in. The Jello nobake boxes can easily be quartered and enjoyed the second night on solo layovers.

Now that I think about it, Boboli Pizza is reeally excellent. Peppers keep at least a week. Shrooms get iffy at some point. Pepperoni lasts forever. The cheese needs to be monitored at room temps but it's just cheese mold plus you're cooking it.
