I need suggestions for new and different raw veggies to munch on
I love to bring raw veggies to work to munch on but I seem to be stuck in a carrots and celery rut with an occassional red pepper thrown in. Can you give me some ideas for expanding my repertoire. I prefer to have the veggies be preppable at home and suitable as finger foods (tomatoes are only eligible in the bite size varieties). Tzatziki is my preferred dipping companion.
I live in Cambridge, MA and have good access to fresh produce.
Yes, I am open to trying the exotic too!

Mustard in a 'toothpaste' tube is sort of an odd way to put it. We Germans put lots of things into tubes. It's cool and convenient. In my fridge right now I have 4 tubes: Senf, Anchovy paste, tomato paste and Harissa (http://www.amazon.com/Harissa-Sauce-Tube-Le-Cabanon/dp/B0019SA1MY)
The more the merrier! BTW, we have mayonaise in a tube in Germany as well!
My favorite - can't live without - German candy are Katzenpfoetchen made by Katjes. The BEST licorice on the planet!
