Garlicky greens
These rich, buttery greens will complement your roast
Heat the oil in a large saucepan and fry the peppers for about 5 mins until starting to caramelise. Add the garlic and chillies, cook for 30 secs, then tip in the tomatoes and olives (if using). Season, add a pinch of sugar, bring to the boil, then simmer, uncovered, for 10 mins.
Meanwhile, cook the pasta according to pack instructions. Heat the grill. Drain the pasta and mix into the tomato sauce, along with the tuna. Tip into a large ovenproof dish. Mix the breadcrumbs and Parmesan together and scatter over the top. Grill for 3-4 mins or until the topping is crisp and golden. Serve with a green salad, if you like.
