Asparagus Pastry Puffs

Directions

1. Preheat oven to 400°. In a large skillet, bring 1-1/2 in. of water to a boil. Add asparagus; cook, uncovered, until crisp-tender, 1-3 minutes. Remove asparagus and immediately drop into ice water. Drain and pat dry.
2. In a small bowl, mix cream cheese, Parmesan cheese, mustard, lemon juice, salt and pepper until blended. Unfold puff pastry sheets; cut each sheet in half to make a total of 4 rectangles. Spread each rectangle with a fourth of the cream cheese mixture to within 1/4 in. of edges. Arrange asparagus over top, allowing tips to show at each end; roll up jelly-roll style. Using a serrated knife, cut each roll crosswise into 4 sections.
3. Place on a parchment-lined baking sheet, seam side down. In a small bowl, whisk egg and water until blended; brush lightly over tops.
4. Bake until golden brown, 25-30 minutes. Remove from pan to a wire rack; serve warm.
