Mix chicken, carrot, green onion, soy sauce, and ginger until combined
Quickly rinse one rice paper sheet (it should still feel slightly firm), then layer a second half-sheet on top
Add ~1.5 Tbsp filling, shape into a rectangle, fold sides, and roll tightly
Repeat with remaining filling and wrappers
Steam in a basket with space between rolls for 8–10 minutes, until cooked through
