Allow your pie crusts to thaw for about 15 minutes, or zap them in the microwave for 20 seconds at 30% power.
Preheat your oven to 350 degrees.
Sprinkle your counter top with a little flour. Roll one of your pie crusts out.
Cut 2 inch circles into your pie crusts with a cookie cutter, cup or whatever circlular object you have.
Place each circle into the opening of a greased mini muffin pan. Press pie crust down into pan. (You should have about 20 pies - one row empty)
In a medium sized bowl combine, mixed berries, 1/4 cup SPLENDA® Sugar Blend, lemon juice and cornstarch.
Scoop about 1 TBS of berry mixture into each pie top. Cut thin 1/2 centimeter strips with remaining pie crust, and then cut those into about 1 1/2 inch pieces and form a mini lattice crust with 4 pieces over the top of each pie. Press the edges of the lattice pieces into the pie crust base.
In a small bowl combine egg and water to make an egg wash. Spread over the top of each pie with a silicone brush.
Sprinkle the tops with remaining tablespoon of SPLENDA® Sugar Blend
Bake for about 25 minutes until crust is golden brown.
Allow to cool for a few minutes before carefully removing each pie from pan and onto a cooling rack to cool completely before serving.
