I am a fan of the mason jar lunches. I make 4-5 at a time and then I just grab one in the morning. If you pack them tightly they stay fresh. I have made mixed salads (I dump it into a bowl at work for easier eating, I even add chopped avocado and just put a slice of lemon on top of the avocado layer and it stays green vs. brown and slimy. I also like quinoa with a balsamic dressing, chopped chicken and whatever else you like such as cranberries and scallions. When I do these, I am much better about having a decent satisfying lunch each day.
