2: Prepare 3 courgettes, then slice fairly thinly, using a mandolin if you have one - it makes the job much easier.
3: Pour 2 tablespoons olive oil into a non-stick frying pan over high heat. As soon as it's nice and hot, add the sliced courgettes and cook for a few minutes. They should still be slightly crunchy. Set aside. If any liquid has come out of the courgettes, drain them thoroughly in a sieve or colander.
5: Wash 1 handful fresh mint leaves, dry and chop roughly with a knife or scissors. You can add any other herbs you like. I have used parley and thyme here, but this is not essential.
6: Pour 200 ml cream into a bowl, add the diced feta, salt and pepper. Add the mint and mix.
7: Preheat the oven to 220°C (430°F). Take the pastry case out of the fridge, and arrange the courgette slices in the bottom.
8: Pour the cream-feta-herb mixture on top, then cook for 30-40 minutes.
9: You can put the tart under the grill for a few minutes at the end to brown the top.
Remarks
For a smoother filling mixture, you can use a hand blender to combine the cream with the feta and herbs. If you don't like feta, you can just leave it out, or replace it with mozarella or a blue cheese like roquefort, but the taste will be very different. The essence of this recipe is the combination of courgette and mint.
