Grate half a large courgette and set it aside in a bowl while you prepare the rest of the ingredients.
Boil the green peas for a few minutes until they are cooked through.
Place them in a mixer with the spring onions, fresh mint and coriander leaves, and feta cheese.
Blend until you get a rough crumbly mixture and empty it into a medium sized mixing bowl. Add the beaten egg and lemon juice and stir together.
Return to your courgette. Take 2 sheets of kitchen paper and press it firmly on top of the grated courgette. This is to squeeze out as much water as you can. Do this twice if you need to and then add the courgette to the other ingredients.
Spoon in the flour and stir everything together. Your mixture will be sticky but it should hold together when you spoon it out.
Heat 1 tablespoon olive oil in a frying pan on a medium heat.
Scoop up some of the mixture with a spoon – a ball about as big as a ping pong ball works well – and place it in the pan of heated oil.
Using two spoons, press down onto the top and sides of the ball in the pan, so that you form it into a round patty. Repeat again for the rest of the mixture. If you need to add another tablespoon of oil for the second batch.
Cook each pea fritter for a few minutes on each side until golden and cooked through. Serve with a spoonful of yogurt for a great toddler meal.
