Heat your waffle iron to medium high. We’re using the awesome Ninja Belgian Waffle Maker PRO NeverStick.
Working in batches of 4 roll, slice the rolls in half. Add raspberry preserves to one side and top with cheese, turkey, and ham slices. Set the sandwiches aside while you make the custard.
In a large bowl, whisk together the eggs and heavy cream. Season with a pinch of kosher salt and few grinds of black pepper.
Dip the sandwiches in the custard and place on the waffle iron. Carefully press the sandwiches in the waffle iron for 3 to 4 minutes or until crisp. Repeat with the remaining sandwiches.
