In a large bowl, whisk together all of the sauce ingredients. Set aside.
Heat 2 tablespoons of oil in a large non-stick pan over medium heat.
Add the ginger, garlic, and scallions and sauté for 1 minute.
Add the cabbage, mushrooms, salt, coconut seeds, and sesame oil. Sauté for 3 minutes, until the cabbage has slightly wilted. Set aside to cool.
Have a large shallow bowl filled about 1-inch with room temperature water ready.
Carefully dip a rice paper wrapping into the water just enough to wet the rice paper, turning to ensure the whole piece is wet.
Slightly wet a cutting board or other flat surface to prevent the rice paper from sticking. Place the rice paper onto the prepared surface, then place 1 Tablespoon of the filling into the center.
Gently fold the bottom half up until it just covers the top of the filling. Then gently fold in the left side, followed by the right side. Finally, carefully roll up from the bottom until you reach the top of the rice paper and gently press to secure the ends. Set aside and cover with a damp paper towel to prevent the dumpling from drying out. Repeat with remaining rice paper wrappers.
Once all dumplings have been formed, heat 2 Tablespoons of oil in a nonstick skillet over medium heat.
Pan fry dumplings in batches so as not to overcrowd the pan for about 3-4 minutes per side, until the dumplings are golden brown. While dumplings are still hot right out of the pan, sprinkle sesame seeds over them. Repeat until all dumplings are cooked.
