Summer vegetable and feta galette

Method

1. Put the feta, herbs and lemon zest in a food processor or blender and whizz into a fine green rubble. Put the sliced shallot in a bowl with your vegetables, the oil and a squeeze of lemon juice, then season with salt and pepper and mix to coat.
2. Heat the oven to 180ºC fan/gas 6 with a large, flat baking sheet inside to heat up.
3. Keep the pastry on the sheet of baking paper it comes in and prick the centre with a fork, leaving a border (around 3-5cm) around the outside. Spread the feta mixture over the pricked centre, then lay the sliced vegetables on top. Fold the exposed pastry borders into the centre to create a rustic pleated edge. Brush the pastry edges with egg wash, then sprinkle with the nigella seeds.
4. Remove the hot tray from the oven and carefully slide the galette (on the baking paper) onto it, then bake in the oven for 20-25 minutes until the pastry base is cooked through and crisp underneath. Once out of the oven, drizzle with a little extra virgin olive oil, then stir the sumac into the yogurt and serve on the side (if you like).
