PREHEAT oven heat to 350°F. Separate dough into 16 triangles. Mix sugar and cinnamon; set aside.
DIP marshmallows in margarine, then in sugar mixture, turning to evenly coat all sides. Wrap each dough triangle around 1 marshmallow, completely covering marshmallow; pinch edges of dough tightly to seal. Dip sealed side in margarine; place, sealed side down, in each of 16 greased medium muffin cups. Repeat with remaining ingredients. Place muffin pan on baking sheet.
BAKE 10 to 15 min. or until golden brown. Immediately remove from pan; drizzle with glaze. Sprinkle with walnuts. Serve warm.
