I do the leftover thing too, but sometimes I just don't want to repeat or DH eats it before it gets packed up. Lol.
Sometimes I'll take salads, but more often than not I'll make a wrap in a ww tortilla or make something to stick in a ww pita.
I actually just made my lunch for tomorrow. I cut a ww pita in half and stuffed it with 1 cup of fresh spinach. Then I put 1/2c of garbanzo beans in a small tupperware container with 1T of vinegarette dressing. I'll put the beans in the pita at lunch tomorrow. I keep them separate so nothing gets soggy.
Some other ideas:
~tuna salad with whole grain crackers and raw veggie sticks
~plain yogurt with fruit, chopped nuts and sweetener of choice (I like a little maple syrup)
~grain salad (quinoa, bulgur, leftover rice, etc. tossed with cooked veggies and/or dried fruit and dressing)
~antipasto finger foods in small portions (1 oz of cheese, a few olives, whole grain crackers, artichoke hearts, other veggies, etc.)
Soup is always good too this time of year. I don't take it very often though because our thermos has been used for coffee so much that things put into it taste like coffee.
