To Make the Pastry:

1. In a large bowl, combine the flour and salt.
2. Stir through the tahini, then use your fingertips to crumble it through evenly.

4. Roll the pastry onto a sheet of baking paper to a thickness of about 3-5 millimeter.
5. Line a baking tray with the pastry and set aside.
6. Preheat the oven to 350°F.

To Make the Filling:

1. Finely chop the leek. Add the leek and 1 tablespoon of water to a frying pan.

3. Meanwhile, blend the remaining ingredients: 2 cups water, cashews, lemon juice, salt, garlic, and arrowroot powder.
4. Add the blended mixture to the frying pan with the leek.
5. Continue to cook while stirring until the cheesy mixture thickens, should take about 1 minute.
6. Pour the cheesy leek mixture into the pastry.
7. You can fold over the remaining pastry, like a galette, or trim if desired.
8. Bake for 40 minutes.
