1. In a sauté pan over medium heat, wilt the spinach with 2 tablespoons of water, stirring occasionally. Transfer the wilted spinach to a colander and squeeze the spinach to remove the moisture before chopping the spinach finely.
2. In a bowl, combine 1 ½ teaspoons soy sauce, sesame oil, sherry, salt, sugar and white pepper. Mix in the ground turkey, scallion, ginger and spinach. Chill for 10 minutes.
3. Dust a cookie tray with cornstarch and set aside.
4. Arrange 4 wonton wrappers on a work surface, (keeping the other wrappers covered with plastic wrap so they don’t dry out) and brush the edges of the wrappers with water.
5. Spoon 1 teaspoon of turkey and spinach filling in the center of each wonton and fold the wrapper diagonally over the filling to form triangles and press to seal. Transfer to the baking sheet and continue with the remaining wrappers.
6. Meanwhile prepare the sauce in a large bowl by combining soy sauce with the chile oil, sesame oil, garlic, cilantro and sesame seeds, stirring until well combined.
7. After all the wontons are filled and sealed, cook the wontons in a large saucepan of boiling water, stirring occasionally. When the wontons float, cook for 3 minutes longer. Drain the wontons well.
8. Add the wontons to the bowl with the sauce mixture and toss to coat and serve immediately.
