What vegetarian dish should I make for a small dinner party tonight?

I'm big fan of eggplant. http://recipes.epicurean.com/recipe/213/eggplant-parmigiana.html

Parmesan risotto-stuffed portabellos, a mixed greens salad with fresh herbs and rosemary bread

squash soup - butternut squash (good with some pear or apple chunks in it), or zucchini soup (made with carrots and celery, thyme, broth, lots of zucchini, then pureed with your immersion blender) ... carrot soup is also good - add some ginger

i also second eggplant parmesan

sweet potato and blue cheese quesadillas (in the Whole Foods Cookbook if you have it, but not online unless you get to it on Amazon) --- off the top of my head --- saute a 2-3 cups (total) of chopped onion, bell pepper, garlic, roasted poblano chile (or another), add 4 cups of mashed sweet potato, about 2 inch-cubes of crumbled blue cheese - mix it well - spread some out on a tortilla (1/2 cup to 1 cup depending on the size of your tortilla, and get really close to the edges), sprinkle a thin layer of grated monterey jack (a few tablespoons or so depending - it'll be 1 1/2 cups total), put another tortilla on top, place on an oiled baking sheet, heat at 350 or so for 5 minutes (until cheese melts and it's all warm), slice like a pizza, eat immediately ---- repeat this process for the rest (this makes 3-6 whole quesadillas depending on how big) - so i recommend making them all up and then sticking them in the oven just before the party, or otherwise keeping them warm ----- it's ALWAYS a winner!

The sweet potato/blue cheese quesadillas sound spectacular.

my mouth is watering just thinking about them.... i made them for my grandma last week, she loved it!

moussaka (kind of like lasagna, but different, and with eggplant). or enchiladas.
