In a bowl, combine all the ingredients of the Filling together. Set aside.
Mix all the Sauce ingredients together until well combined, then set aside.
To wrap the wontons, place about a teaspoon of the filling in the center of a wonton wrapper. Dip your index finger into a small bowl of water and trace the outer edges of the wrapper. This will help seal the wontons.
Fold the wonton to form a triangle shape. Pinch the edges of the wrapper to seal tightly, ensuring there are no leaks. Then, using the thumb and index finger of both hands, pinch and fold both corners of the wonton downwards.
Next, lift the right corner over the left corner and pinch to seal tightly. You can dab a little water on both corners to help secure the seal. Transfer the wontons to a floured surface or a plate lined with parchment paper to prevent sticking.
Bring the water to a boil. Gently drop all the wontons into the water and stir them gently with a ladle to prevent sticking. Boil the wontons until they float to the top, about 1-2 minutes. Transfer the wontons immediately using a strainer or slotted spoon. Shake off any excess water and transfer the wontons to a bowl.
Add the desired amount of the sauce to the wontons and gently toss them to coat evenly. Transfer the wontons to a serving platter, garnish with sesame seeds, and serve immediately.
