Spray counter lightly with non-stick cooking spray. Combine rolls and roll into a 10x15-inch rectangle. Place dough on a sprayed baking sheet. Poke with a fork several times to prevent bubbles from forming and spread with softened butter.
Combine sugar, nuts and cinnamon and sprinkle over the buttered dough. Bake at 375°F 12-15 minutes or until golden brown on the edges. Combine glaze ingredients and drizzle over warm flat bread.
