Cook the fava beans in salted water, let cool and peel. Measure out the amount needed. Place lettuce leaves on a plate. Grate the kohlrabi into thin flakes, place on the lettuce, sprinkle with tarragon leaves and halved, pitted cherries.
Crumble the feta and sprinkle over the salad. In a bowl, mix olive oil with syrup, lime juice, parsley, pink peppercorns ground in a mortar, season with sea salt and freshly ground pepper, and drizzle over the salad.
