Preheat your oven to 350°F (175°C).
Lightly coat a baking dish with cooking spray.
Dice your bread and drained peaches into even cubes and place in your baking dish.
In a bowl, whisk together the eggs, almond milk, zero-point sweetener, vanilla extract, ground cinnamon, salt and nutmeg.
Pour half of the egg mixture over the bread.
Add in your diced peaches and gently incorporate.
Pour the remaining egg mixture evenly over the peaches.
Bake for 30-35 minutes or until the casserole is set and golden brown.
Remove from the oven and let it cool slightly before serving.
Garnish with fresh mint leaves, or a sprinkle of zero-point sweetener.
