You can solve the problem of "no microwave" by purchasing a food thermos. Then you can take soup, stew, chili, casserole, etc.... and it will stay nice and warm till lunch time.
You can solve the problem of "no fridge" by purchasing an insulated lunch box or bag, and/or one of those little lunch-box ice packs. You can take salad, sandwiches, hard boiled eggs or anything else that needs to be kept cool, this way.
Most fruit does just fine without refrigeration for a few hours. Some are actually much better unrefrigerated (tomatoes, peaches).
My husband enjoys individual packets of beef jerky... surprisingly not even bad on the calories (but ohhh sodium!).
Dried fruits and nuts are handy, but you have to really watch the portion size on these calorie-dense items!
Bagels pack well with or without refrigeration.
