Spread strawberry jam on one side of the bread slices.

Place one slice of ham on the jam-covered bread.

Add a slice of cheese on top of the ham.

Place the second slice of ham on top of the cheese and cover with the second slice of bread.

Mix the egg and milk together in a bowl.

Dip the sandwich into the egg mixture, ensuring all sides are coated. Let it soak for about 5 minutes.

Heat a pan with butter or oil on low heat and cook the sandwich slowly. Start with the top and bottom, then cook the sides.
