Part of the reason I love this dish is its versatility. Mix up your fish selection by using halibut, black cod or even salmon, add shrimps or take out the squid – it all tastes wonderful. You can also replace the fish with cubed chicken breasts, if you prefer. Cut the fennel, pepper and zucchini into a small dice so they look attractive in the finished dish. If you are not strictly following the Mediterranean way of eating, then include 3 ounces of chorizo sausage for flavouring.
