I had never heard of this sandwich until I saw a friend a work eating one and she told me how she made it. I made ours savory with mustard and mayo, but it you prefer sweet you can skip that and drizzle with syrup, jelly or jam.
Put pan on stove and turn on to medium high heat and spray bottom and sides with spray oil.
Mix eggs, milk and cinnamon in a bowl.
Beat until well mixed
Dip bread in egg mixture on both side and then place in pan to toast for a few minutes. Check to see if toasted and when toasted flip and toast on the other side. Continue until all slices are toasted.
Once both sides are toasted, place on baking or cookie sheet and spread and alternate spreading one piece with mustard and the other with mayo.
Alternate putting a slice of Swiss Cheese on one side and 5-6 slices of ham on the other side of the toast. Preheat an oven to 300 degrees.
Put sandwiches together and place in the oven for 5 minutes or until the cheese is melted. Put on plate then serve.
