Step 2: For the salad, put the sliced kohlrabi and fennel in a bowl, season, add the rest of the rapeseed oil and white wine vinegar.

Step 3: Put the potatoes in a pan of boiling water and cook for 15-20 minutes. Drain, lightly crush and add the rosemary oil.

Step 4: Place all the ingredients for the salsa verde in a blender, season and blitz until smooth.

Step 5: Season the lemon sole fillets, pour a little rapeseed oil in a pan and cook the fish for three minutes on one side, flip over and cook for a further minute. To serve, spoon some of the crushed potatoes on a plate, add some beetroot, salad and mustard leaves. Place the sole on top and finish with a drizzle of salsa verde.
