Beat egg until foamy; add sugar
and cinnamon; beat to blend.
Spread about 1 1/2 tbs. of the mixture on
each slice of bread; place slightly apart
on foil-lined cookie sheet.
Bake in 400F oven until sugar bubbles
out from underneath the meringue-like top,
about 15 min. Serve at once.
Makes 10 slices.
