Put the yoghurt, lemon juice, salt, pepper (amount according to taste), pressed garlic in a shaker beaker and finally add the herbs and shake vigorously. Check the dressing to taste and consistency. If it is too thick for you, you can give a little milk and possibly some sugar because of the lemon juice.
Of course you can also add other herbs. These are the ones that I always have fresh, so I really liked the combination.
