My vote...bunch of ramen packets.
Pro tip: when you're going to a dinner served by people who can't cook, bring this and doctor up your food yourself. I swear to God, bringing your own spice shaker makes even the dullest food palatable.

Toiletries: Enough for the entire deployment. Ship's store will run out when you need them the most and might not carry the brand you use. Make sure you have an extra toothbrush.
Shower Shoes: Bring two pairs just in case one of them gets nasty, falls apart, or is stolen (it will happen).
Spices: Bring your own for chow because meals can be bland. Go to the camping section at Walmart or on Amazon and buy Coghlan's Multi-Spice which has paprika, curry, cayenne, garlic salt, black pepper, and salt. Maybe some hot sauce, too.
Drink Mix: Grab a few boxes of on-the-go Crystal Light or something similar. I like the grape & strawberry flavors with caffeine. I recommend the powder over the liquid stuff (to include Mio). They last longer and are easier to pack. The caffeinated drink mix helped out a lot while on watch, especially if you don't like coffee.
Snacks & Food: Food for backpacking trips is great because they take up little room. I brought beef jerky, slim jims, tuna packs, and instant oatmeal
Flashlights: Different types. Get one you can hang, one you can wear on your forehead, and one you can hold. I recommend at least one of them have a red light option. Depending on your watch, this could be handy. Bring extra batteries.
Undergarments: Enough socks, underwear, and undershirts for two weeks. Foot powder is a must!
Advancement: Bring all the patches and devices you need for the next pay grade. If you advance while deployed, you'll be glad you have them! Bring advancement material so you can study!
Universal Travel Adapter: When you are out and about and need to plug in your phone while in port at a restaurant or bar, it will come in handy when you need to charge.
Journal: Keep notes of your adventures. I never did this but wish I did. It would be amazing for you to log your deployment so you have something to remember when talking to your kids & grandkids. You'll have a lot of stories but will never remember them all.
I like to take this camping.

--Lentils: high protein, quick cooking, cheap, can season for different kinds of meals. Dry lentils will be much lighter than canned/bagged/cooked lentils. Boil for 25 minutes.
--Quinoa: same as above! Use it like rice. It only needs to boil for about 15 minutes.
--Baked chickpeas. Do this ahead of time and pack servings in ziplock baggies. High protein, crunchy, delicious. Here's a simple recipe.
--Homemade trail mix. Nuts, seeds, dried fruits, chocolate chips, etc.
--Avocados. These need to be eaten within 2-3 days of buying them (if they're hard), but easy to cut in half and eat with a spoon and salt. The fat in avocados is awesome.
--Spices. You'll be set with salt, pepper, paprika, oregano, garlic powder, onion powder, and cumin. You could get something like a Multi spice jar or ziplock baggies.
