MIX pork, cabbage, onions, egg and 2 Tbsp. each of the dressing and soy sauce until well blended. Spoon evenly onto won ton wrappers, adding about 1 tsp. of the pork mixture to each wrapper. Moisten edge of each wrapper with water; fold in half to form a half-moon, pressing edges together to seal. If desired, edges can be pleated with five or six folds.

HEAT 2 tsp. of the oil in large nonstick skillet on medium-high heat. Add 10 dumplings; cook 1 to 1-1/2 min. or until bottoms are golden brown. Gradually add 1/4 cup of the water; cover. Reduce heat to medium-low; cook 2 to 2-1/2 min. or until filling is cooked through and water has evaporated. Remove dumplings to serving plate; wipe skillet dry. Repeat with remaining dumplings.

COMBINE remaining 2 Tbsp. dressing, remaining 2 Tbsp. soy sauce and remaining 1 Tbsp. water. Serve as a dipping sauce with the dumplings.
