Preheat oven to 325 degrees.

In a small bowl, combine the strawberries, blueberries and yogurt. Mix together. Set aside.

Unroll the pie crusts and cut into 9 pieces. Repeat with the other pie crust. Put 2 similar squares together and press 3 of the sides together.

With the 4th side open, add the berry and yogurt mixture into each of the raviolis you created. Press the last side together to make sure that none of the goodness comes out. You could even use a fork to smash each side.

Place each ravioli on a prepared cookie sheet and bake for about 10 minutes or until golden brown.
