Boil the potatoes for 15 mins until tender. Meanwhile, line a grill pan with foil and brush with a little oil. Put the fish on the foil, brush with oil and sprinkle lightly with salt and pepper. Grill the fish for 6-8 mins depending on thickness, until the flesh flakes easily.
Drain potatoes, then return to the pan and stir in the peppers, olives and garlic. Gently stir in the mayonnaise. Serve the fish with rocket and warm potato salad.
