<human>: My friend's little brother is really suffering in his dorm. He's lost 15-20 pounds because he's totally at a loss at how to deal with his food situation in his dorm. Of course, he is kinda naive, so that's part of it too.

Anyways, four young men share 3 rooms, and they have to split two teeny tiny fridges between them. The fridges are specially chosen to hold 2 dining hall containers each, which is supposed to be "enough" food to survive on.. so, we can basically leave these fridges out of the equation, which leaves us with a situation of: no fridge, no hot plates allowed, no appliances of any kind.

He is, however, located a 10 minute walk away from at least one full service grocery store!

So, I'm looking for suggestions for meals/hearty snacks that can be prepared from 100% shelf stable ingredients. I'm pretty sure he is willing to eat straight from cans as long as the result isn't too gross. I know there are many things commonly kept in the fridge that are actually still okay to eat if left out for a couple days, so if you guys have suggestions about things like that, it would be very helpful too!

Here's what I have come up with so far:

-Peanut butter + jelly + banana sandwiches. Can be made pretty thick, delicious, and nutritious!  
-Shelf stable cheese and apple, sliced and served with crackers  
-Pickles.. I know they say refrigerate after opening, but surely they won't kill you if make sure to consume the jar within a couple days. Probably not hard to do between 4 dudes.  
-Canned pears/peaches  
-Canned cheese ravioli.. I actually quite enjoy these straight out of the can, unheated.  
-Buy a pie from the grocery store to consume over a couple day period  
-Beef jerky  
-Cereal with shelf stable almond milk.. they could open one milk per day, share between the four of them so the milk is consumed immediately

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Dorm room with no fridge, no stove, no appliances. Need meal/snack ideas made from 100% shelf stable ingredients.
