Heat oven to 425°F. Line 2 cookie sheets with cooking parchment paper. In medium bowl, toss apples with lemon juice. In small bowl, mix 1/4 cup sugar and the apple pie spice; sprinkle over apples, tossing to coat.
Remove pie crusts from pouches; unroll on lightly floured work surface. Roll each crust to 10-inch round. Using 4-inch round cutter, cut out 16 rounds. Place 8 rounds on each cookie sheet. Place 1 apple wedge off-center on each round. Brush edges of rounds with egg. Wrap and press edges together; seal with fork. Brush tops with remaining egg; sprinkle with 1 tablespoon sugar.
Bake 14 to 16 minutes or until crust is golden brown. Remove from cookie sheets to cooling rack; cool at least 10 minutes.
In small microwavable bowl, microwave caramel bits and milk uncovered on High 1 minute, stirring once, until caramel can be stirred smooth. Drizzle caramel over wedges.
