Wash 100g spinach leaves then heat in a pan until wilted. Remove from the heat and set aside to cool.
If making a chia/flax egg grind 1 tbsp seeds in a food processor then mix with 3 tbsp water. Set aside for a few minutes until you have a gloopy paste.
Put the 100g wilted spinach into your blender and pulse until broken down. Add the remaining ingredients (125g wholemeal flour, 1 tsp baking powder, 1 egg or chia/flax egg, 200ml milk, 1 tbsp oil and pinch of nutmeg) and blend on high speed until well combined.
Cook for 3-4 minutes on each side before turning over with a spatula and cooking the other side. Cooking them slowly is key here so they don't burn on the outside before they're cooked in the middle.
