Creamy macaroni bake with Mediterranean sprinkles

Preheat the oven to 190ºC, gas mark 5. Cook the macaroni in boiling, lightly salted water for 8 minutes, then drain well, reserving some of the cooking water.

Heat the oil in a large saucepan and fry the leek gently for 3 minutes, until softened. Add the garlic and fry for 1 minute more. Stir in the cheese sauce, olives, pea and bean mix, tomatoes, macaroni and plenty of black pepper. Heat through for 2 minutes, until hot, mixing in enough reserved cooking water to keep the sauce loose. Tip everything into a large, shallow baking dish and spread level.

Sprinkle over the cheese, followed by the Mediterranean crust. Bake for 20 minutes, until crisp, golden and piping hot throughout
