Heat sausage patties according to package directions; cut into bite-size pieces. Cut a pocket in the crust of each slice of bread. Butter the inside of pocket. In a small bowl, combine sausage and cheese. Stuff into pockets.
In a shallow bowl, beat the eggs, milk, sugar and cinnamon; dip both sides of bread. Cook on a greased hot griddle until golden brown on both sides. Serve with syrup if desired.
