Toss all ingredients into the blender and blend for about 20 seconds until the mixture is smooth. Leave the batter for 15 minutes at room temperature if you are making them right away or cover and leave in the fridge for the next morning.
Heat up a crepe pan (or non-stick frying pan) and add a tsp of olive oil. Pour in approx 3/4 cup of batter in your pan and swirl the batter around the pan until the batter is evenly spread. When the crepe just begins to have some browning, use a spatula to loosen and flip the crepe and cook for another 30 seconds or until it's done.
