A few days ago, I came across a package of rice paper in my pantry and was inspired to make a trio of summer rolls. Any combination of ingredients that make a good chopped salad also will make a good summer roll. Rice paper starts out rigid and it easily cracks and crumbles. Place a sheet into a dish of warm water for 10 seconds and the paper is suddenly flexible. Set it down, mound your filling across the bottom third, and by the time you're rolling it up the paper is very soft and a little sticky -- so it rolls with ease, and the finished roll holds together.
