Heat oven to 375°F. Grease large cookie sheet, or line with cooking parchment paper; set aside. Unroll dough on work surface. Press into 13x8-inch rectangle. Spread hazelnut spread evenly over dough to within 1/4 inch of edges. Sprinkle with hazelnuts, reserving 1 tablespoon for topping.

Roll up dough starting at longest side; pinch to seal.

Place seam side down lengthwise in middle of cookie sheet.

Using sharp knife, slice dough lengthwise to form 2 halves.

Twist halves together with cut sides of dough facing up. Shape into circle; gently pinch ends together. Brush with beaten egg; sprinkle with sugar and reserved hazelnuts.

Bake 20 to 22 minutes or until golden brown. Serve warm.
