Heat a skillet over medium-high heat and add the diced onions, cooking for 2-3 minutes until they begin to soften and become translucent. Add the ground turkey, onion powder, and garlic powder, breaking the meat apart with a spoon as it cooks. Stir frequently for 5-7 minutes until the turkey is completely cooked through and no pink remains. Remove from heat, stir in the freshly minced garlic and sesame oil, then let the mixture cool for several minutes before assembling—this prevents the rice paper from tearing when it comes into contact with hot filling.
Fill a shallow bowl with warm water. Working with one rice paper at a time, dip it into the warm water for about 10-15 seconds until it becomes pliable and soft—don't oversoak or it will tear. Lay the softened rice paper flat on a clean surface, place a lettuce leaf in the center, then add about 2-3 tablespoons of the cooled turkey filling from Step 1 on top of the lettuce. Fold the sides of the rice paper inward and roll tightly away from you, creating a compact cylinder. I like to keep a damp towel nearby to wipe my hands between rolls—it prevents sticking and helps you work more efficiently.
Heat a skillet over medium-high heat and lightly coat with avocado spray oil. Once the skillet is hot, carefully place the assembled dumplings seam-side down in the pan (work in batches if needed to avoid crowding). Cook for 3-4 minutes until the bottom develops a light golden-brown color, then flip and cook the other side for another 3-4 minutes. The pan-searing creates a slight texture contrast and locks in the flavors before the final baking step.
Preheat your oven to 400°F while the dumplings are finishing their pan-sear. Transfer the pan-seared dumplings to a baking sheet or rimmed tray and bake for 8-10 minutes until the rice paper becomes slightly crispy and the dumplings are heated through. This two-stage cooking method ensures the filling is fully cooked and the texture is ideal—crispy on the outside but tender inside.
Transfer the baked dumplings to a serving plate and serve immediately while still warm. Set out small bowls of coconut aminos and red pickled ginger on the side for dipping and garnishing. The umami-rich coconut aminos pairs beautifully with the ginger's bright, spicy notes to complement the savory turkey filling.
