Heat oven to 200C/180C fan/gas 6.
Make 3-4 slashes on each side of the
fish. Rub in the seasoning, lime zest and
oil, making sure you get it right into the slashes and the cavity. Place on a
baking tray lined with foil and bake
for 12-15 mins or until just cooked through.
Turn the grill to high and cook
for 2-3 mins more to char the skin.
Cover and rest for a few mins.
For the salsa, mix the mango, chilli,
avocado, spring onions, coriander and
lime juice, and season. Bring a small pan
of water to the boil, add the beans and
cook for 4 mins, then drain. Serve the
fish with rice, beans and salsa.
