WAY LATE to this thread, but some ideas:
-instant noodles OKAY instant noodles, but hear me out: the bowls of tonkotsu ramen from Costco are god-tier and make a decent meal on their own
- beef jerky, nuts, trail mix, any snacky thing with protein
- fresh or dried fruits so you can get that fiber in
- protein shakes are also god-tier to keep you going
- any kind of bar food, like you are already thinking: Larabars, Kind bars, Cliff bars, whatever your preferred bar
- I have a friend who brings those pre-packed crustless PB&Js. I've also been known to bring a loaf of bread, peanut butter, and something sweet (jam if you have a fridge, honey if not)
- If you have a fridge in your hotel, you can upgrade to lunch meats and such
- Also can bring salads, yogurts, and other fridged things if you have a fridge
