What are some quick summer meal ideas?

Looking for quick summer meal ideas!!

Hey Everyone, I work alot. And my normal schedule hours are 3-11 pm. So generally I'm only eating 1 meal a day, while at work. Before 3pm it's far too hot to cook anything, and I don't want to cook or eat much when I get out of work at night. I'm looking for fresh simple summery meal ideas that I can easily make ahead of time, and bring to work with me. I'd like things that will keep in the fridge for a few days, so that I can eat them more than once a week. Or make them in advanced. Obviously I can do sandwiches, but ick I'm getting soooo sick of sandwiches!! I'm thinking of trying more salads, and things. Anyone got any recipes or ideas?

P.s. I prefer organic, and vegetarian dishes, however, if you have a great recipee that uses chicken or animal products I'll consider it :)
