In a glass bowl, thoroughly combine the wonton filling ingredients. Set in the refrigerator until ready to use, allowing the flavors to meld.

Lay out wonton wrappers on your cutting board a few at a time, oriented diagonally with a corner facing toward you. Wet each corner of the wrapper with a little water. Add a round tsp of filling to the center. Fold the corner facing you over the top of the filling, and press it to the opposite corner, making a triangle facing away from you. Fold the corners of the triangle together at the bottom, allowing the top corner to naturally fold over.
