Place the spelt flour, gram flour, baking powder, salt and pepper in a large bowl and leave to one side.
Place the broccoli, courgette, spinach, milk and harissa in a blender and blitz until completely smooth.
Mix the wet mixture into the dry by gradually stirring until everything is combined without any lumps.
Heat a frying pan over a medium heat. If you are using a non-stick pan, there is no need to add any oil.
Pour 2 tablespoons of the mixture into the pan. You can fit 2-3 pancakes in at a time if you have a large frying pan.
Turn the heat down to low and cook on the first side for up to 2 minutes. You will see the pancake is cooking through by the air bubbles which start to form on top.
Flip the pancakes over and cook for just 20 seconds more, before removing from the pan and leaving on a cooling rack while you cook the remaining pancakes.
Continue until you have used all the mixture, or have made as many pancakes as you need. Any extra mixture can be stored in an airtight container for a few days until you are ready for more pancakes.
