Instructions
Olive Crust
Pre-heat the oven to 180 °C
Sift the flour/salt. Whisk the egg yolk with the olive oil. Add the yolk/oil mixture to the flour and combine with a fork, adding 1/4-1/2 cup of the warm water until it comes together.
Knead briefly to form a ball. Don't overwork. Roll out the pastry and fill a 22cm loose bottom tart tin. Cover and leave to rest in the fridge for about 30 minutes.
Prick the base and bake blind for 10 minutes.
Endive and Feta Filling
While the tart is resting, mix the feta, yoghurt, nutmeg, teaspoon of flour and eggs in a food processor until you have a creamy mixture. You may need to squish the feta a little to get it to combine. But don't worry; a few small lumps are okay.
Add a dash of olive oil to a large frying pan and saute the onions; when they start to take on a little colour, add the endive (garlic if using). Add a good grinding of black pepper and the dried herbs. Saute until sealed, golden and caramelised on both sides. You don't need to add salt—the feta does that for you.
Layer the onions and endives in a circular pattern into the pastry case. Pour over the feta mixture - making sure there is an even layer.
Bake for 30 - 35 minutes or until the tart is golden and risen.
