Line a sieve with a cheesecloth or muslin cloth, and set the sieve over a bowl. Place the yogurt with a pinch of salt in the lined sieve, and let it drain over the bowl for 6-8 hours in the refrigerator. You can drain the yogurt for upto 24 hours for a thicker, more cheese-like labneh.
Once drained, gently squeeze out any excess liquid from the yogurt.
Empty into a bowl and top with olive oil and black pepper or zaatar if desired.
To make the salad:
Prepare the labneh and top with some olive oil and finely grated garlic. Set aside.
Cut the boiled beetroots and carrots into similar sized matchsticks. Quickly blanch the carrots (optional).
In a bowl, place the beetroot and carrot matchsticks with the olive oil, red wine vinegar, lemon juice, sugar, salt, and pepper. Add the chopped parsley and coriander and mix to combine. Taste and adjust seasoning.
In a serving bowl or plate, spread the labneh on the bottom. Top the yogurt with the beetroot and carrot mixture, and garnish with torn mint leaves. Season with fresh black pepper before serving, either slightly chilled or at room temperature.
