Recipes That Make Good Lunches for Work?

Hello, all! This is my first foray into the kitchen and food forum, as I usually hang out over in beauty. I am looking for some new ideas and thought you would be able to help :-) I like to make a batch of "something" every week and take it for lunch during the week. I bring my lunch 4 days out of the week, and I don't mind eating the same thing on those days, but I do need some new and fairly easy recipes that make nice lunches. (I have a little tiny crockpot that warms my lunch on my desk too!) I'd love your ideas, all - thanks so much in advance :-)
