Start by seasoning the aubergine slices with salt and pepper and oregano and pan-fry on both sides to brown. Place on a baking tray and cook for 15-20 minutes. Top with the salsa or pizza sauce, cherry tomatoes, sliced mozzarella and finish off with some grated Parmesan and a drizzle of olive oil. Place under a hot grill for 5 minutes. To serve, place the aubergine pizzas onto a large wooden platter and decorate with fresh basil leaves and extra grated parmesan
