Preheat the oven to 180C/350F/Gas 4.
In a bowl, mix together half of the cheese, the breadcrumbs and parsley and season with salt and freshly ground black pepper.
Pile the mixture into the hollowed-out tomato. Top with the remaining cheese and drizzle with olive oil.
Place onto a baking tray and bake in the oven for 12-15 minutes, or until the cheese is bubbling and starting to turn golden-brown. Serve.
