I had the idea to do a "meatless Monday" for reasons of health, and, more importantly, creativity in the kitchen.

So, here's where you come in:
I need ideas.

Good vegetarian dishes and recipe websites are welcome, but what I really need is some lunch ideas.

Armed with only a fridge and a microwave at work, what can I do to limit my consumption of pb&js and reheated leftovers for lunch?

Thank you,
and bon appetite!
