3. Add the tomato purée to the onions and fry for a minute, then add the cherry tomatoes, parsley and sugar. Season, then bubble for 20 minutes, stirring occasionally. Pour onto the fennel and bake for 45 minutes more.
4. Meanwhile, fry the breadcrumbs in a little oil until golden, then sprinkle over the bake with the grated cheese for the last 5 minutes. Serve sprinkled with extra chopped parsley.
