I always sent leftovers with my husband to work but he had a micro to reheat. With that said.....I always like cold green beans with a little Italian dressing. I also liked cold steak strips. If he likes salmon, shrimp, chicken, you could make nice salads with a variety of things on top with the protein added. I love artichokes, cukes, tomatoes, mushrooms, olives, cheese (grated), boiled eggs, bacon bits, etc. on top. Pretzels are a great snack and easy to eat as you drive. Grapes are good and easy. However, the key to all this is to get him things he likes. You have some really great ideas here so, good luck!
