Preheat your oven to approx 190. Put the pieces of fish onto a sheet of tin foil. Pour over a glug of oil, wine and a squeeze of lemon juice. Cook for 15 minutes.

Chop your potatoes into even sized chunks and add to salted boiling water. They will probably need around 12 minutes (dependent on size.)

Cut the ends off your beans and add them to the potatoes. They need 10 minutes.

Five minutes before the fish is cooked, half your tomatoes and add them to the oven tray.

Strain your beans and potatoes. Serve everything with a big wedge of lime.
