"Rice paper is a low-calorie, gluten-free option in comparison to wheat-based products. This delicate, translucent vegan dumpling allows the diner to see the colorful nutritious vegetables, which are bursting with vitamins. Another serving option is to create a rice wrap by leaving one end open, allowing the vegetables to cascade onto the plate creating a delicious display."
Combine 1 tablespoon sesame oil, tamari, hot water, and chia seeds in a small bowl. Allow to bloom for 15 minutes.
Combine bloomed chia seed mixture with mushrooms, carrots, shallot, leeks, ginger, Chinese five-spice powder, and pepper in a bowl. Fold filling ingredients together thoroughly.
Fill a large, shallow container with cold water. Soak rice paper, 1 at a time, until pliable, about 10 seconds. Lay softened rice paper on a plate, rough side up. Scoop a heaping tablespoon of filling near an edge of the rice paper. Fold left and right edges in toward the center, then fold top and bottom edges in to create a large dumpling. Repeat with remaining rice paper and filling.
Place a steamer insert into a saucepan and fill with water to just below the bottom of the steamer. Brush remaining sesame oil onto the insert to keep dumplings from sticking. Bring water to a boil. Add dumplings, cover, and steam until tender, about 3 minutes.
