Whisk and spoon the marinade over the salmon and cook for 15-20 minutes. Plunge the broccoli into a saucepan of boiling water and cook for 3 minutes. Drain and refresh in ice-cold water immediately.
Bring to a gentle simmer and cook the salmon for 3–4 minutes, turning occasionally (add an extra splash of water if the sauce thickens too much.) Drain the pasta and broccoli and return to the pan.
