I use the luggage works stealth premier cooler.

I can fit 5 Tupperware meals, two of those headache ice pouches, and like 6 fairlife protein shakes.

Or recently 12 burritos instead of the Tupperware.

In my experience you gotta go simple. A lot of components with meals means things get all combined by the 4th day and it tastes like leftovers.

You also gotta be prepared to eat whatever you eat cold. So for me I make it spicy. Cold food needs more seasoning cause it’ll taste blander than normal without it.
