For flatbreads. Place flour, baking powder, salt and cumin seeds into a bowl. Mix in enough yoghurt using a wooden spoon until the dry ingredients come together. Use floured hands and a little extra flour to knead briefly to form a soft dough. If too sticky, add flour, if too dry, add yoghurt. Divide into 6 portions.
Roll each portion out between two flour-dusted pieces of baking paper. They should be rustic and freeform, about ½ cm thick.
Heat a griddle pan until smoking hot. Drizzle the flatbreads lightly with olive oil. Grill until charred on both sides and puffed up slightly. Set aside. Brush with optional garlic butter for extra deliciousness.
Mix the smoky tahini yoghurt ingredients together and season to taste.
Toss the thinly sliced courgettes in a little olive oil and season with salt.
Grill for a few seconds per side on a hot griddle pan – just to allow some char marks. Don’t overdo it. Use a pair of tongs to gently remove them from the griddle pan.
Gently toss the spinach, grilled courgette, rocket and mint together with a drizzle of Willowcreek lemon flavoured olive oil.
Spread smoky yoghurt onto each flatbread and top generously with tossed greens, crumbled chevin and seeds. Drizzle once more with olive oil. Sprinkle with coarse salt and pepper. Serve remaining smoky yoghurt on the side.
