Begin by layering thin slices of deli ham, turkey breast, and Swiss cheese between two thick slices of brioche or challah bread. Press down gently to help the layers adhere together.

In a medium-sized mixing bowl, whisk together 2 large fresh eggs and ½ cup of whole milk until frothy. Add a pinch of salt. This mixture is key to the custard-like coating.

Carefully take each sandwich and dip it into the egg mixture, ensuring both sides are evenly coated. A quick dip will allow the batter to cling without soaking.

Heat a skillet over medium heat and add 1-2 tablespoons of butter until melted. Cook the dipped sandwiches for 3-4 minutes on each side until golden brown.

Once golden brown and the cheese is melty, transfer to a plate lined with paper towels. Dust the tops with powdered sugar.

Slice the sandwiches in half and plate with a small bowl of maple syrup on the side.
