Preheat oven to 350F.

Spray 4 small oven safe dishes (mine are 4 1/2" in diameter) with nonstick cooking spray. Toss peaches, cinnamon, cornstarch, and brown sugar in a bowl. Divide among dishes.

Pulse together flour, ginger, salt, nutmeg and sugar in the bowl of the food processor. Add butter and pulse until mixture resembles coarse crumbles (if you don't have a food processor, use your fingers to pinch together the mixture). Top the dishes with crumb mixture.

Bake for 30 minutes.
