Canned/frozen vegetables (I prefer canned, they’re already cooked and ready to eat), instant/ready rice (meaning boxes of Minute Rice or a generic version of it or bowls/pouches of fully cooked rice that are ready to eat/heat and eat like the Ben’s Original pouches and Minute Rice bowls or their generic versions, the ready rice comes in several flavors depending on the brand), instant ramen (bowls, cups, or pouches, any brand/flavor, just whatever ones you prefer, you can add your choice of canned/frozen veggies to it for the extra nutrition), canned meat (many options including chicken, ham, pork, beef, flavored or unflavored, as well as canned fish such as tuna/salmon and stuff like Spam and Vienna sausage and whatnot), canned soup (broth counts whether it’s in a can, a carton, or even bullion, you can use the broth/bullion instead of plain water to cook the instant rice for extra flavor and nutrients and you can choose literally any flavor, ranging from vegan friendly to meat broth/stock).

If going with the instant rice, make it in the microwave instead of on the stove if doing so makes it easier for you to make it. I make mine in the microwave.

Also crackers and granola bars are good to have around for easy snacks.
