To prepare filling, chop shrimp and place in medium bowl. Stir in 1 egg white, scallions, salt, pepper, scallions, ginger and garlic.
To assemble wontons: place wonton skins on work surface and then place 1 teaspoon of filling in the center of each skin; brush edges with remaining egg white and fold diagonally to form a triangle. Press edges to seal (if desired join the two bottom edges, one over the other, sealing with egg white or leave s triangles).
In a pot of boiling water cook wontons for 1 minute. Remove with a slotted spoon to a serving bowl and sprinkle with soy sauce (or add to chicken broth, seasoned with soy sauce for won ton soup).
