Rinse the lentils under running water, then put them in a jug. Add the water and soak them for 3 hours.
Transfer the lentils with the soaking water to a blender.
Add the garlic and spinach.
Blend until you have a smooth batter - the thickness should be similar to single cream.
Add a spoonful of vegetable oil (this is optional, but it will prevent the wraps sticking to the pan).
Lightly spray or grease a non-stick frying pan with oil, then heat it over medium heat.
Using a small ladle, spoon some batter into the hot pan and, using the back of the ladle, spread it out evenly into a circle.
Cook for about 3-4 minutes or until the surface is no longer wet and you can move the wrap easily with a spatula.
Flip the wrap and cook for another 2-3 minutes.
Remove the wrap to a plate then make more wraps, using up the batter.
Serve at room temperature.
