Grilled mackerel with green bean, olive and tomato pesto salad

Method

1. Heat the grill to medium. Put the mackerel fillets, skin-side up, on a large baking sheet. Brush with oil and season with salt and pepper. Add the sourdough pieces to the baking sheet, drizzle a little oil over the bread, then cook under the grill for 6-8 minutes, turning the bread once, until the mackerel is heated through and the bread is crisp and golden.
2. Meanwhile, bring a pan of water to the boil, then add the green beans. Cook for 3-4 minutes, drain and run under cold water. In a small bowl, mix the pesto with half the lemon juice and 2 tbsp cold water.
3. Put the bread, green beans, olives, tomatoes, pesto mix, rocket and parsley in a large mixing bowl and toss together thoroughly. Season to taste (you may want a little more lemon juice), then serve with the mackerel.
