01 - Roll each bread slice with a rolling pin until thin and pliable for easy rolling.
02 - Arrange ham, turkey, and Swiss cheese evenly across each flattened bread slice.
03 - Roll each bread slice tightly into a log, pressing gently to seal the seam.
04 - Whisk together eggs, milk, salt, and pepper in a shallow bowl until fully combined.
05 - Dip each roll up in the egg mixture, turning to ensure all sides are evenly coated.
06 - Melt butter in a large nonstick skillet over medium heat. Add roll ups seam-side down and cook, turning occasionally, until all sides are golden brown and cheese is melted, about 6-8 minutes.
07 - Transfer to a serving plate, dust generously with powdered sugar, and serve warm with raspberry jam for dipping.
