This peak-fall-flavored pie is made in a sheet pan, so it’s easier to cut and large enough to feed a crowd. No more struggling cutting a perfect circle for that bottom pie crust, either—it’s a big rectangle that’s much easier to get right on the first try. It’s warm and comforting inside with cranberries, pears, and fresh ginger for zing, and topped with streusel for ultimate buttery, sugary, crunchy goodness. Whipped cream to finish is nice, but a scoop of vanilla ice cream wouldn’t hurt...
