Mine was to grab a big bag of the cheapest rice at the Asian supermarket and a bulk bag of black beans. Cook rice and beans then mix with soy sauce/black pepper. If I had eggs I would add a fried egg for breakfast or hard boiled for lunch / dinner.
While the stove was broken I would poke holes in potatoes with a fork and microwave them until soft. Salt & pepper or whatever seasoning you had. Butter was a great addition to this if it was around.
For a side dish or snack I would often do ramen coleslaw. Smash up the ramen noodles and pour over a whole bag of Cole slaw. Pour the seasoning packet on top of that. Toast almond slivers then at the end add some sesame oil to warm up the oil. Pour the almonds and oil into the slaw and mix.
If it makes you feel any better I came back from an international trip at some point when this was all being reported on and neither myself, my partner, nor anyone I saw had their phones searched or was pulled aside. They asked what kind of trip it was, how long we stayed, where we went and if we had any alcohol, tobacco, or food.
We were traveling from Europe back to a “blue” State if that means anything. I would imagine the process would be more stringent depending on where you’re coming from.
If you do end up going you should definitely still consider encryption + backups and logging out of or deleting apps you are signed into. You could also bring a cheap barebones burner or work phone if you have one. There are plenty of articles online that describe the process of protecting your privacy when traveling abroad and returning.
Good luck!
