Dice the onions and cut the garlic into slices. Simmer in a little water with the grained clear soup and herb salt until soft.
Add the pre-cooked lentils and bring to the boil again.
Whisk all ingredients in a hand mixer and season.
Preparation Tip:
If you like to cook with fresh herbs, it's best to get kitchen herbs in pots - that way you'll always have everything on hand!
