Soak the lentils with the water for 4 hours or overnight. You can rinse and drain the lentils and replace the drained water with around 1/4 cup of fresh water (or leave and blend in the soaking water).
Preheat the oven to 180c/350f.
Pour the lentils into 2 small piles on a baking sheet, then use the back of a measuring cup or spoon and gently spread the mix to create a thinner round pizza shape.
Place in the preheated oven and cook for 12 minutes until they are no longer wet (you will be able to peel them off the baking sheet).
Top with your toppings (we listed ours above) and bake for a further 5 minutes until the cheese has melted.
Slice and serve.
Store leftovers in the fridge for 3 days, or freeze (with or without toppings for up to 2 months).
