Mix yogurt with oil, lemon juice, concentrated apple juice, grated horseradish and grated (or very finely chopped) cucumber to make a salad dressing. Grate the apples into the sauce with the peel on a coarse grater, peel the beetroot and grate on a fine grater.
Garnish with sunflower seeds if you like.
Tastes super delicious as a starter salad with white bread or with grilled meat!
