Preheat oven to 220C. Lay a baking tray with non-stick baking paper.
Cut aubergines in half diagonally and sprinkle some salt on the flesh. Let them soak off for few minutes.
Place aubergines on the baking tray, flesh facing down, and transfer to the oven. Roast for 30min or until soft. Once cooked let them cool off before handling.
Scoop out the flesh of aubergines from the skins. Place in a medium bowl. Add tahini, lemon juice, crushed garlic, and parsley. Give it a good mix and season with salt to taste.
Place in a serving dish and drizzle olive oil on top. Serve with a side of freshly toasted nan bread.
