Cheap and healthy-ish hotel meals ideas? (Manitoba, no knives, no microwave)

An organisation I volunteer with is flying me out to Manitoba for an event and paying for my hotel, I'm a full time artist so obvi money is tight and I don't want to eat out for every meal. I'm flying so I can't bring a knife, I'm only there for 4 days/3 nights, I'm sharing the room with 2 other people so I need to be conscious of the mini fridge space I use and the hotel room doesn't have a microwave
