Cut salmon into approx. 2 x 2 cm cubes. Grate lemon and lime peel and squeeze out the juice.
Mix both with brown sugar, grated ginger, chopped chili pepper and olive oil. Add a little salt and marinate the fish with it, covered, in the refrigerator for 10-15 minutes.
For the salsa, remove the tomato stalk and seeds, and finely dice the rest. Clean the young onion, cut into fine rings. Cut red onion into very fine strips. Cut garlic into thin slices and finely chop the parsley.
Mix everything with coriander, honey, vinegar, olive oil, salt and pepper and let marinate for about 5 minutes. Season to taste.
Lift fish out of marinade, drain and arrange on plates with salsa. Serve immediately.
