1. In a medium bowl, stir together the first five ingredients. Set the mixture aside.
2. Dust your work surface with flour. Unroll one of the pie crusts and use a circular cookie cutter or the rim of a cup to cut it into 12 (2 3/4-inch) rounds. Gently press each one into a well of a mini muffin tin. Fold any excess dough over the well's rim. Repeat with the second pie crust.
3. Heat the oven to 375 degrees . Gather the dough scraps and roll them out to a 1/8-inch thickness. Use tiny cookie cutters to make holiday shapes or cut the dough into thin strips for a lattice top. Add a generous tablespoon of filling to each pie shell. Arrange the dough pieces on top. Seal the edges of the lattice tops with a toothpick.
4. Brush the tops of the pies with egg wash. Bake them until the filling begins to bubble and the crust turns golden brown, about 15 minutes. Let them cool in the pan before serving.
