I think you'll have more luck looking for summer rolls. I have most often
seen spring rolls that are fried, whereas summer rolls use the water-soaked
rice paper and are not fried.

Sorry, but my favorite recipes for summer rolls use chicken or shrimp. I
have seen a recipe for vegetable summer rolls on epicurious.com (type summer
rolls into the search box), but haven't tried it.

ingredients...It kind of depends on where you live -- my area has a lot
of good Asian groceries, and even the American supermarkets carry some good
Asisan products. But in some areas, it may be impossible to find that
stuff. The rice paper might be the hardest thing to find. Or fish sauce,
if you choose a recipe with a dipping sauce that requires fish sauce, which
many do (and yum, it's worth finding!). You can also use a peanut sauce for
dipping.
