Chicken and Mushroom Wellington

Thaw pastry 25 minutes. Meanwhile, prepare sauce and filling: In 1-quart saucepan, heat beef-flavored broth, wine, and porcini mushrooms to boiling over high heat. Reduce heat to medium and simmer mixture until reduced to about 2/3 cup. Strain broth mixture into small bowl and reserve porcini mushrooms. Stir 1 tablespoon butter into strained broth mixture and set sauce aside. Finely chop porcini mushrooms and set aside.

In large skillet, heat remaining 1 tablespoon butter over medium heat. Add onion and sauté 5 minutes. Stir in rosemary and cook 1 minute. Add spinach and 1/4 teaspoon salt; cover tightly and cook 2 minutes or until spinach is wilted. Remove from heat, add reserved chopped porcini mushrooms, and set aside.

Heat oven to 375 degrees F. Lightly grease a baking sheet. On lightly floured surface, unfold one puff pastry sheet (1/2 package) to a 9-inch square. With rolling pin, roll out pastry to a 12- by 10-inch rectangle, smoothing any creases. Cut pastry into 3 pieces: a 12- by 3-inch strip, a 7-inch square, and a 7- by 5-inch rectangle. Repeat rolling and cutting with remaining puff pastry sheet.

On both 7- by 5-inch pastry rectangles, place a portabella mushroom upside down. Top each mushroom with chicken breast half and sprinkle with remaining 1/4 teaspoon salt; top with spinach mixture. Brush some egg mixture on pastry around mushroom; cover each chicken-and-vegetable filling with 7-inch pastry square. Press gently around filling to seal top pastry to bottom pastry. Trim edges to make round. With spatula, transfer each filled pastry round to greased baking sheet.

Garnish tops of rounds: From remaining 12- by 3-inch pastry strips, cut eight 6-inch-long by 1/4-inch-wide strips and twenty-eight 1/2-inch diamonds. Brush top of each round with egg mixture; top with pastry strips and diamonds arranged in alternating rows. Brush lightly with egg mixture and bake 25 to 30 minutes or until pastry is puffed and golden brown. Cool 5 minutes.

Meanwhile, reheat sauce and divide between 2 serving plates. Place each filled pastry in sauce and cut in half to reveal filling. If desired, serve with baby vegetables and garnish with rosemary sprigs.
