Rinse the fish inside and out under cold running water. Dry with kitchen paper.
Rub the outside of the fish with a little olive oil, as this helps to create a crispy skin.
Season the cavity with a little salt and pepper, and stuff with the lemon or lime slices.
In a bowl mix the chopped vegetables with a little olive oil, seasoning and vinegar until well coated.
Place vegetables on a roasting tray, and place fish on top.
Bake in a hot oven for approx 15 – 20 mins until cooked.
Remove and serve.
