Prepare the dressing. Finely chop the herbs and add them to a bowl with a pinch of salt and vegan yogurt. Stir together until smooth, creamy and combined. If the dressing looks a little thick, you can thin it with a tablespoon of water.
2 tablespoons plain vegan yogurt, 2 tablespoons fresh mint and parsley, 1 tablespoon lemon juice, 1 tablespoon water, Pinch of salt
Chop the remaining ingredients. Dice the apple into small 1 cm pieces and discard the core. Slice the celery thinly, about 2mm thick, into little half-moons. Half the red grapes. Break up any larger walnut pieces so they're all nice and small.
1 small to medium green apple, 40 g celery stick (1 small stick), 80g (½ cup) red grapes, 30 g (¼ cup) walnut pieces
Toss the salad. Place the celery, fruit and walnuts into a bowl, then pour in the Waldorf salad dressing. Gently toss it together with a spoon until everything is evenly coated with dressing. Do a taste test and add more salt or a squeeze of lemon juice if needed.
Serve with lemon wedges and green salad leaves (optional).
handful of cos or romaine lettuce, lemon wedges
