For the carrot salad with coconut and seared tuna, boil the carrots in a little salted water for 5-7 minutes until soft. Immediately rinse with cold water and set aside.
Mix the ingredients for the dressing and season well with salt and pepper.
Cut the tuna into slices. Heat a frying pan until hot, add peanut oil and sear the fish slices on both sides for 1 minute each. Then roll in the sesame seeds.
Cut tuna into small fillets, season with coarse sea salt and drizzle with lime juice. Marinate the carrots and arrange on a plate. Spread remaining marinade on top.
Garnish carrot salad with coconut and seared tuna with chervil and serve immediately.
