Whisk dressing ingredients together and season with salt and pepper.
Mix the lettuce with a small amount of dressing, just enough to barely coat the leaves. Place in a bowl to the side.
Pour some warm water into a large shallow dish. Submerge one rice paper round in water until it begins to soften, about 45 seconds. Place on a sheet of parchment paper. Place a small amount of lettuce in the center of the rice paper. Tightly roll into a cylinder, enclosing the lettuce. Repeat with the remaining rounds. Cover with a dampened paper towel or wrap in plastic. Chill. Can be made 4 hours ahead.
When ready to serve, remove from plastic and cut each roll into 2-inch-long pieces. Stand upright on a platter and top with a spot of dressing. You can put crumbled pancetta, Parmesan cheese, or chopped nuts on top for flavor and garnish.
