Boil the pasta in plenty of water until cooked al dente, then drain.

While the pasta is cooking, heat a dash of oil in a large frying pan, and add the diced tomatoes and garlic. Cook over a medium heat for 5 minutes, until they've cooked right down to create a chunky tomato sauce.

Add the mixed herbs, salt and pepper, and sugar (if using). Finally add the chopped basil and mascarpone cheese, and stir until the cheese has melted. It will create a creamy, glossy sauce.

Transfer the drained pasta to the pan with the sauce, and mix well. Serve topped with parmesan-style cheese, if desired.
