Heat a frying pan with oil and start sealing the whiting fillets. In a pan, cook the carrot and the sweet potato (al dente). After cooking, take it to the same skillet that you sealed the fish and sauté with more oil.
In the sauce, just add the ingredients (mustard, honey, lemon, curry and black pepper) and mix well. Serve with crisp lettuce and season with salt and pepper to taste.
