Spread a thin layer of strawberry jam on each slice of bread. Sandwich the slices together with the jam in the middle.
Cut the sandwich into 3 sticks.
In a bowl, whisk together the eggs, milk, vanilla extract, and cinnamon.
Dip each bread stick into the egg mixture, coating all sides.
Heat butter in a pan over medium heat. Cook the sticks until golden brown on all sides.
Serve warm with your favorite dipping sauce.
