We had cereal, granola bars, PB sandwiches and roll-ups (on tortillas). I also had lunch meat, cheese and pepperoni in the room for snacks. We had the QS meal plan, but my boys eat a lot!
I did also bring an electric skillet to warm up leftovers, or to make omelets in the morning.
We flew, so I packed a suitcase with the room temp foods and put a thermal bag with ice packs in one siutcase with cheese. We then had a grocery delivery for other items.
