1. Season the salmon fillets with salt. Squeeze the lemon. Peel the carrot and zucchini, cut them into tagliatelle-like strips using a vegetable peeler. Cut the smoked salmon into strips. Place the salmon fillets in a glass casserole dish, drizzle with lemon juice and 100 ml of water. Cover and cook for 5 minutes in the microwave (750 W). Keep warm in the casserole dish.
2. In a saucepan, bring a large amount of salted water to a boil, cook the tagliatelle for 8 minutes. Drain while reserving the cooking water. Put the pasta in a serving dish, add the margarine and parmesan, mix and cover. Bring the pasta water back to a boil, poach the vegetable tagliatelle for 3 minutes. Drain and add them to the pasta along with the salmon strips. Remove the skin from the salmon fillets, cut them into cubes and gently incorporate them.
3. In a bowl, mix the yogurt, ketchup, and oil. Heat for 1 minute in the microwave (400 W). Season with salt and pepper. Pour the Marie-Rose sauce over the preparation. Garnish with basil.
