Place the frozen peas into a small bowl and cover with boiling water. Leave them to one side for 5-10 minutes until soft, before draining.
While the peas are soaking, whisk the gram flour, lime juice and eggs together in a large bowl until a thick, smooth mixture forms.
Once the mixture has come together, crumble in the feta using your hands, grate in the courgettes and add the drained peas, chopped chives and a good pinch of salt. Mix well until the whole mixture comes together.
Place a large non-stick pan over a medium heat and add a drizzle of olive oil. Once the oil is warm, add 2 tablespoons of the fritter mixture and smooth out a little using the spoon to create a circle shape. Cook the fritter for 3-5 minutes on each side until golden on the outside and cooked through. Repeat this process with the rest of the fritter mixture until you have all of your fritters; you can usually cook three in a pan at a time.
