Preheat your oven to 180C / 350F.
Add garlic to a chopping board along with the peel of half a lemon, parsley and salt. Use a knife to chop until finely chopped. Add half of it to a small mixing bowl along with 1 tbsp olive oil yogurt and mix until well combined.
Use a sharp knife to cut your potatoes in half, then cut in six slices. Turn them on their flattest side and cut even sized chips.
Add to a large mixing bowl along with 1 tbsp olive oil, salt and sesame seeds. Mix to coat the chips. Place on a baking tray making sure you space the chips apart. They mustn’t be touching otherwise they won’t crispen up. Bake for 20 minutes or until golden and crispy.
Sprinkle with remaining herb mix, crumbled feta and more chopped parsley.
