Preheat the oven to 350 degrees.
Place the two cans of peach pie filling into a mixing bowl, and add in 1 tablespoon of cinnamon. Stir to combine.
Layer the peach pie filling mixture into the bottom of a greased 9x13 baking dish.
Make a single layer of six pieces of white bread on top of the peach filling.
In a mixing bowl, combine the eggs, milk, vanilla, and dash of nutmeg. Whisk to combine all of the ingredients well.
Pour half of the mixture over the slices of bread in the baking dish.
Place another layer of white bread onto the top of the casserole in the baking dish.
Pour the other half of the egg mixture over the new layer of bread slices.
Bake the casserole for 15-20 minutes until cooked through and browned on top.
Let the casserole cool for a few minutes, and then invert onto a serving plate or cutting board. Serve immediately.
