Make about half a recipe for quarter sheet pan.
The pan in the recipe (18x13) is technically a half sheet pan.
A quarter sheet pan (9x13) is half the size of the recommended pan.
(See Wikipedia for full details.)
The recipe calls for making the pie in a 10 x 15 inch pan; you cut out one piece of dough to 18 x 13, which allows you to run it up the sides and pull those side pieces onto the top edge.
Quick arithmetic shows that you should use 60% of the dough for the bottom and 40% for the top; it's easiest to get this right, of course, by using a scale. ;o)
Hi ya
I have--you can math it out for yourself, but a quarter sheet (9x13) is 25% fewer square inches than a jelly roll (10x15), so I just made the recipe roughly as written and held back 1/4 of the filling to make a mini-pie with the extra pastry dough.

That person offered some additional detail about what was done.
