01 - Flatten the bread slices with a rolling pin until thin and pliable, creating an even surface for rolling.
02 - Place a slice of ham, a slice of turkey, and a slice of Swiss cheese on each flattened bread piece.
03 - Roll each bread slice tightly into a log, pressing gently along the seam to seal completely.
04 - In a shallow bowl, whisk together the eggs, milk, salt, and pepper 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, swirling to coat the bottom.
07 - Add the roll ups seam-side down and cook, turning occasionally, until all sides are golden brown and cheese is melted, about 6-8 minutes total.
08 - Remove to a serving plate, dust generously with powdered sugar, and serve warm with raspberry jam for dipping.
