You can use lots of different kinds of bread for this--cinnamon raisin, brioche--whatever you have. Your dad likes this with maple syrup. I like strawberry preserves.
1 C milk or cream
1 tbl sugar
1/4 tsp cinnamon (optional)
1 tsp vanilla
a pinch of salt
sliced bread, 4-6 slices depending on their size
butter & oil for frying
Beat the egg in a shallow dish and add remaining ingredients except for bread. Heat 1 tsp butter & 1 tsp oil in a non stick skillet over medium high heat. Add bread 1 or 2 pieces at a time to custard and let it soak up the mixture. Don't let the bread soak so long that it falls apart. Place bread in skillet and cook until browned and puffed, turning once. Continue cooking bread until all the custard mixture is gone, adding butter and oil when necessary.
You can sift confectioners sugar over the toast if you like. Serve w/ maple syrup and strawberry preserves
