• Change the flavour of this dish by altering the marinade. For an Asian flavour, use the zest and juice of 1½ limes instead of the lemon, use fresh coriander instead of basil, and add chopped red chilli (as little or as much chilli as you like). Use lime wedges on the skewers, and grill quartered red and green capsicums alongside the fish instead of the zucchini.
• Other fish that work well in this recipe include salmon and large raw prawns.
