Beat the egg, milk, vanilla, and cinnamon together in a
flat dish such as a soup plate or pie pan, that will
accommodate the bread and make
it easy to remove the bread once it's wet.
Add 1 slice of bread at a time, turning so that both
sides are coated and absorb some of the
liquid. Remove the bread, slice by slice, to a plate.
Heat butter or oil on a large griddle or skillet, reduce
the heat, and brown the bread briefly on each side. Serve
with syrup, honey, cooked or raw fruit, or plain.
