In medium bowl, combine all ingredients except wonton skins and spray coating; mix until well blended. (To prevent wonton skins from drying out, prepare one or two rangoon at a time.)
Place 1 teaspoon filling in center of each wonton skin. Moisten edges with water; fold in half to form triangle, pressing edges to seal. Pull bottom corners down and overlap slightly; moisten one corner and press to seal.
Lightly spray baking sheet with vegetable coating. Arrange rangoon on sheet and lightly spray to coat.
Bake in a 425 degree F oven for 12 to 15 minutes, or until golden brown.
Serve hot with sweet and sour sauce or mustard sauce.
