This warming one-pan family dish is packed with winter vegetables and topped with a rich cheese sauce. It’s great for a midweek meat-free meal.

Preheat the oven to 200C/180C Fan/Gas Mark 6. Heat the oil in a large ovenproof frying pan over a medium heat. Add the onion and cook for 4-5 minutes until softened. Stir in the garlic and cook for a further minute.

Add the cauliflower, courgette and mushrooms and cook, stirring, for 5-6 minutes, then stir in the tomatoes, spinach and oregano. Season to taste with salt and freshly ground black pepper. Pour over the pasta sauce and turn gently to coat the vegetables. Drop spoonfuls of the passata on top and scatter over the grated cheese.

Bake in the preheated oven for 25-30 minutes until golden and bubbling. Garnish with freshly chopped parsley and serve straight from the pan with toast or crusty bread.

No Pan, No Problem: If your frying pan is not suitable for use in the oven, transfer the vegetables to a large shallow baking dish before pouring over the cheese sauce.
