Lay out the bread slices and build two sandwiches by placing 2 slices of ham, 2 slices of turkey, and 2 slices of Swiss cheese between two slices of bread. Gently press down to compact the fillings. Trim the crusts if desired for a traditional presentation.

In a shallow dish wide enough to fit the sandwiches, whisk together the eggs, milk, salt, and black pepper until well combined and slightly frothy.

Place a large skillet over medium heat and add the butter. Allow it to melt completely and coat the bottom of the pan evenly.

Carefully dip each sandwich into the egg mixture, turning to coat both sides thoroughly. Let any excess drip off, then immediately place the sandwiches in the hot skillet. Cook until golden brown and crispy, about 3-4 minutes per side. Ensure the cheese is melted and the egg coating is set.

Transfer the cooked sandwiches to a paper towel-lined plate to absorb excess butter. Let rest for a minute, then dust the tops with powdered sugar using a small sieve or shaker. Cut each sandwich diagonally into two triangles and serve immediately with raspberry jam on the side.
