Preheat the oven to 180°C.
First, coat the feta in the flour followed by the eggs, then dip into the dukkah to cover completely. Place on a parchment lined tray and bake for 15 minutes until the feta is soft and the dukkah is lightly golden. Remove from the oven and set aside.
Meanwhile, make the dressing. Place the lemon juice and oil in a large bowl with 1 teaspoon of salt and a good grind of pepper. Whisk well and add in the tomatoes, melon and ¾ of the herbs. Mix to dress and place on a serving platter with all of the dressing.
Roughly break the feta and scatter between the tomatoes and melon.
Serve with the remaining herbs scattered on top.
