HEAT oven to 375ºF.
COMBINE pears, cheese, lemon juice and 1 tsp. cinnamon. Mix remaining cinnamon and trail mix. Stack 2 phyllo sheets; brush lightly with 1 Tbsp. margarine, then sprinkle with 1/3 of the trail mix. Repeat all layers twice.
SPREAD with pear mixture to within 1 inch of edges. Roll up jelly roll-style, starting at one short end and removing foil as phyllo is rolled. Place, seam-side down, on parchment paper-covered baking sheet. Brush with remaining margarine.
BAKE 40 to 45 min. or until golden brown. Cool slightly. Top with sifted icing sugar.
