POACHED Pears: Cook first 4 ingredients in pan large enough to completely cover the pears with liquid. Add pear halves; simmer on medium-low heat 20 min. or just until tender, stirring occasionally. Drain pears.
SPICED Walnuts: Hand beat egg whites until frothy. Add remaining ingredients; stir until nuts are evenly coated. Spread onto bottom of parchment-lined half-sheet pan. Bake in 350ºF convection oven 5 to 7 min. or until nuts are dry. Cool.
CREAM Cheese Spread: Mix ingredients until blended.
FOR each plating (3 servings): Arrange 3 cake slices on plate; spread each with about 1-1/2 Tbsp. Cream Cheese Spread. Cut each of 2 pear halves into 8 lengthwise slices; fan about 5 pieces on each cake slice. Sprinkle evenly with 1-1/2 Tbsp. Spiced Walnuts and 1 tsp. ginger. Serve with 2 Tbsp. chocolate sauce.
