Fill a shallow pan (a pie pan or 9″ round cake pan) with an inch of hot water. Lay an damp and place it next to the dish. Make sure your prepared fillings are within reach.
Place one rice paper in the water and let it rest for about 15-20 seconds. The rice paper should be pliable but not super floppy. Carefully lay it flat on the towel.
Leaving about 1 inch of open rice paper around the edges, cover the lower third of the paper with a few pieces of lettuce, followed by some cabbage, shredded carrots, cucumber, avocado, basil, and cilantro.
Fold the lower edge up over the fillings, rolling upward just until the filling is compactly enclosed. Fold over the short sides like you would to make a burrito and roll it up.
Place on a large plate and lay a damp towl on top to keep it from drying out.
Serve immedietly with your favorite peanut sauce.
