Jason and I had this for the first time while on our honeymoon. It's now a faviorte in our house.
2 tbsp. milk
4 slices bread
4 tbsp. butter
4 thin slices ham and or turkey
4 slices Swiss cheese
1 tbsp. powdered sugar
Mix together eggs and milk. Dip bread in egg mixture, coating thoroughly on one side. Heat butter in large skillet over medium to low heat, place bread egg side down in skillet. Place the swiss down on the bread in the skillet, and then the ham followed by another peice of cheese. I really like provolone with this too. I guess you can use any cheese.
Cook until the bottom is done to your liking. Dip another peice and put it egg side up on the sandwich allready in the skillet. Then flip the entire sandwich to brown the other side.
Cut in half and sprinkle powered sugar over the top. I like to have a small amount of syrup to dip in.
