Pour olive oil (half a teaspoon) in a nonstick pan, heat it up and add the salmon fillets. Season with a little pepper, then add the coriander, parsley and bay leaf, white wine and lemon juice. Cover and simmer gently 15 minutes. Meanwhile prepare the mushrooms, wash the zucchini and cut into strips. In another pan, pour the remaining oil, quartered mushrooms, zucchini strips and the cooking liquid from the salmon. Bring to a boil at high heat with the pan uncovered. Cook the pasta and serve alongside the salmon on a bed of mushrooms and zucchini.
