the egg, milk and cinnamon in a large bowl.
2. Soak your bread slices in the egg mixture. I like to let mine sit in the batter for 2-3 minutes, until each slice has really soaked up the liquid, but if you like your French Toast more bread-y, and less spongy, you can just dip each slice quickly, just enough to cover both sides.
3. Heat a skillet on medium-high, with a tiny bit of oil (just enough to lightly coat the pan).
4. Cook each slice of French toast on both sides until good and brown. You'll probably have to cook in batches, so keep cooked slices warm in a 200F oven while you work. Serve with real maple syrup.
