Add the rinsed lentils to a bowl and pour boiling water over to cover completely.
Soak for at least 3 hrs (or overnight), then rinse and drain well.
Add the lentils along with the other ingredients to a food processor and blitz to a creamy batter.
Pre-heat a non-stick frying pan to medium and add a little oil.
Add a ladle of the batter and swirl to create the crepe.
Allow to cook for 2-3 minutes until the crepe bubbles and comes away easily at the corning.
Flip and cook on the other side for a minute.
Repeat with the remaining batter.
