Dump the ball of dough out onto a well-floured counter or smooth surface. Roll dough out into a square large enough to fit your pan. About 1/8-1/4 inches thick is best.
Gently press pie crust into edges of a 10x15inch pan and cut off any excess dough. (Repair any tears with excess dough or roll out again for decorative leaf embellishment)
To use premade pie crust:
You will need 2 total pie crusts.
Place a pie crust on a lightly floured surface. Place another pie crust directly on top of that. Roll out the pie crusts until you have a large rectangle, one that fits a 10x15 sheet pan. Trim off any excess crust and repair any tears if needed.
If you want to make decorative leaf embellishments, you will need an additional pie crust.
