How about cucumbers, turnips, pea shoots and shredded napa cabbage with an oriental dressing or cucumbers, corn, tomatoes, onions and romaine with a creamy dressing.
But don't even worry about themes or special veggies. Just use what you currently have. Here's my first one:
I have my deity dressing on the bottom (thank you Happy Herbivore). Next you'll see garbanzo beans, then I also have red bell pepper, cucumber, pea shoots and carrots.
I can get lettuce at our dining hall so all I have to do is dump my veggie jar right on top of the lettuce and voila!! The goodies are right on top of the lettuce and the dressing can run down through it all. Wonderful. And tasty.
My friend at work took one look at what did and that evening made her very own. Exact same thing in two separate jars! You can see all her goodies! Leave out the zucchini in her top layer and you can stuff a lot of spinach or lettuce, maybe some arugula in there. OH MY!
Doesn't this make taking lunch to work seem much more manageable? I used to pack up a bag with about 4 different containers just for ONE salad. Wait. Make that 5 because there is always the dressing!
Give it a shot. And if you do, please take a photo of it and email it to me at firstname.lastname@example.org! Looking forward to seeing your pictures.
