Cut bread 1 1/2 - 2 inches slices. (I recommend Brioche or Challah bread)
Cut pocket in top of bread, down about 1 inch from the bottom.
Fill the pocket with the filling of your choice.
Place bread in custard and soak for approx 30 seconds. Repeat on both sides of the bread.
Cook pocket on griddle at low temperature (approx 300 degrees). Until outside is done, and inside is warm.
