Most supermarkets carry those pop top tiny tuna cans and white chicken breast chunks that are very decent and high in protein for such a small amount of food and no carbs. When I am on the road a lot, a bag of beef jerkey strips is good with a big bottled water for a good snack. (i know , it's so expensive for these bags). Maybe just plan ahead and cut some fruit up and have it in your fridge in tuperware containers becasue that is ultra expensive buying fruit salad anywhere. Raw almonds are a great snack too to pick at. Maybe just try to have as much balance as possible. Plus you want to eat some things you at least like, it's hard to be consistently eating foods that you hate just becasue they are good for you, you'll end up reaching for more crap foods in the long run that way.
