Crépes: Mix all the ingredients. Heat a nonstick pan on medium heat. Take the pan off the heat and pour about a quarter cup of the batter into the pan. Give the pan a quick swirl to coat it evenly with the batter. Return pan back to the stove and cook until the crépe is golden brown on the bottom. Flip it over and cook until golden brown on the other side.
Fold it in half and then again in half. Drizzle with reduced balsamic vinegar and serve. (To make balsamic drizzle, heat balsamic vinegar over medium heat until it boils, turn down heat and let it cook for a couple minutes).
