Spinach and Ricotta Cannelloni

This classic Italian vegetarian main dish can be prepared ahead and cooked from frozen.

Hands-on time 35min. Cooking time about 1hr. Serves 6

FOR THE TOMATO SAUCE

1tbsp extra virgin olive oil

2 garlic cloves, crushed

1tbsp mixed dried herbs

3 x 400g tins plum tomatoes

1tbsp balsamic vinegar

Small handful basil, leaves picked and roughly chopped

FOR THE FILLING

500g spinach

350g ricotta

50g Parmesan, finely grated

1⁄4tsp freshly grated nutmeg

250g dried cannelloni

FOR THE TOPPING

250g mozzarella

1 For the tomato sauce, heat the oil in a large pan over medium heat. Add garlic and cook for 1min. Add remaining sauce ingredients and some seasoning. Simmer for 30min, stirring occasionally and breaking up the tomatoes with the back of a wooden spoon, until thick.

2 Meanwhile, for the filling, put the spinach into a colander in the sink and pour over a full kettle of just-boiled water to wilt (you may need to do this in batches). When cool enough to handle, lift up handfuls of spinach and firmly squeeze out excess moisture. Roughly chop, then put into a large bowl. Mix in the ricotta, Parmesan, nutmeg and plenty of seasoning. Transfer mixture to a large piping bag fitted with a large plain nozzle (or snip a hole in the bottom).

3 Preheat oven to 200°C (180°C fan) mark 6. To assemble, spread 1⁄2 the tomato sauce in the base of a 2.5 litre ovenproof serving dish, about 35 x 40cm. Pipe filling into each cannelloni tube and arrange in a single layer on top of the sauce. Top with the remaining sauce. Tear the mozzarella into strips and lay on top of the sauce.

4 Cook in the oven for 30min, or until golden and bubbling. Serve with a crisp green salad, if you like.
