Remove crusts from pouches; unroll on lightly floured work surface. With 4-inch round cookie cutter, cut 7 rounds from each crust, rerolling scraps once. Spread about 1 tablespoon cream cheese mixture onto each round to within 1/2 inch of edge. Fold edge of each crust over filling, pleating crust slightly as necessary. Place on ungreased cookie sheet. Brush crust edges with egg.
