100 g Parmesan (or vegetarian alternative, shredded)
125 g mozzarella (torn)
200 g fresh lasagne sheets
5 tbsp breadcrumb
Method
Heat grill to high. Arrange the aubergine slices on a baking sheet, brush with oil and season well. Grill for 2-3 mins each side until golden brown, set aside.
Heat oil in a saucepan. Fry the garlic for 1 min then pour in the passata. Simmer for 10 mins with the oregano, sugar and vinegar, then season and stir in the basil.
Assemble the lasagne in a roughly A4-sized baking dish. Spread a few tbsp of the tomato sauce over the base of the dish, followed by a layer of aubergine. Scatter over some Parmesan and mozzarella, then cover with a layer of lasagne. Repeat, finishing with a topping of Parmesan and mozzarella, and sprinkle on the breadcrumbs.
Allow to cool at this point for freezing, or heat oven to 200C/180C fan/gas 6 and cook the lasagne for 25-30 mins until golden and bubbling.
