Preheat the oven to 350°F (180°C) with the fan on, and set the rack to the upper-middle position.

In a large bowl, combine all the ingredients except the feta. Stir with a spoon until well mixed.

Add the crumbled feta to the mixture and stir again to combine.

Line a baking pan with parchment paper and spread the mixture evenly on top. Drizzle a little olive oil over the top (you can also sprinkle a bit of semolina on top if you like).

Bake for 40–45 minutes, until golden brown. Let cool before serving.
