If they are the clear, white round things (will usually say rice paper in French as they are usually a Vietnamese product ... papier du riz or something like that), throw a wrap party.
Clean and put out:
a bowl of leaves of lettuce. You want them a somewhat pliable variety, butter, boston, even romaine will work (shave out the spine)
Any and all of the following:
Cooked slices of meat and/or whole shellfish. Particularly good is thinly sliced flank steak that has been cooked on the grill, and steamed shrimp (to stretch it, cut them in half lengthwise), but virtually anything cut so that it is tender will do, I've even had meatballs in Vietnamese restaurants. ... and meat can be skipped for vegetarians.
green onions
thinly sliced or julienned cucumbers, celery, carrots
finely chifonaded greens of any kind -- cabbage, spinach, etc.
peanuts
rice noodles or bean threads, cooked, rinsed, chopped, and cooled. Rinse at last minute again to make sure they aren't clumpy.
Try to find some fresh herbs, and pile them abundantly: basil, mint, lemon balm (cannot grown lemon grass here, but lemon balm will grow anywhere), parsley, cilantro, chives.
For each two table settings, put out a pie pan of water. Any shallow bowl will do, it just has to be as large or larger than the rice paper.
Buy or make a variety of sauces: peanut sauce, hot szezuan stir fry sauce, that sweet sauce everyone seems to like (don't myself), chinese hot mustard mixed with soy, tiger sauce, dragon sauce, etc. Any Asian type sauce will do.
Taking the lead, each person soaks their rice paper until it is pliable, then puts it on their plate. Put on a lettuce leaf, then pile on your favorite fillings. Wrap, dip, eat. Fun for kids as this is very messy. I recommend giving everyone a towel in lieu of a napkin.
Yes, a do-it-yourself Vietnamese burrito. Called a summer roll in some restaurants.
