My friend Terryl makes a fancy version of this by making her own dough from scratch. Ok - so mine isn't from scratch, but it sure is good.
Ingredients
1 supermarket ready pie crust, uncooked
2 ripe peaches, sliced in about 16 wedges each
1 small basket blueberries
zest from 1 lemon (just the yellow outside)
2 tablespoons sugar
3 tablespoon flour
1 egg, beaten
Directions
Combine peaches, blueberries, sugar, 1/2 the flour and lemon zest - mix carefully so you don't mash up the fruit
Fold a piece of aluminum in half but still large enough to fit under pie crust and dust with remaining flour - lay pie crust on top
Place fruit mixture in middle of crust and fold sides around it making sort of a series of pleats - it will not cover the fruit, but will come a couple of inches up the sides, sort of tart-like
Brush sides of dough with beaten egg
Lift and place foil with pie on grill preheated to medium - not directly overtop of heat if possible
Close lid and cook until dough is beautifully browned and fruit has softened, about 20-25 minutes
