Spread one side of each slice of bread with cream cheese mixture. On half the slices, layer macerated strawberries. Place the other halves on top to form a sandwich.
In a shallow dish, whisk milk, vanilla, sugar, eggs, cinnamon, and nutmeg.
3 eggs, 2/3 cup milk, 1/2 teaspoon cinnamon, 1/4 teaspoon nutmeg, 1 tablespoon brown sugar, 1 teaspoon vanilla
Preheat a cast iron skillet or griddle to medium heat, then melt butter on it.
Dip sandwiches into the egg mixture to coat each tide, then place on griddle or skillet and cook each side 2-3 minutes until golden brown.
