For the crust, place the flour, cheese, salt and pepper in a bowl and mix to combine. Add the butter and amasi (or the yoghurt and water if using) and stir to combine then bring together and knead gently to form a dough. The mixture won't be very wet, but add some water if it is too crumbly to press together.

For the filling, melt the butter in a large fry pan or saucepan over medium heat. Add the onion and season with salt and pepper then cook for 3-4 minutes until softened. Add the garlic and cook for another minute then add the spinach leaves and cook for 2 minutes or until wilted then stir through the basil.
Remove from heat and cool.

Combine the eggs, yoghurt and the cheddar and season with salt and pepper. Add the cooled spinach mixture and stir to combine then add to the tart shell and distribute the mixture evenly. Sprinkle over an extra handful of cheddar if you want it extra cheesy.

If you want to go the extra step, make the green oil by combining all the ingredients and a decent pinch of salt in a bowl, stir and drizzle over to serve. Alternatively just serve warm with a wedge of lemon.
