Peel and finely dice the shallot and garlic. Wash and clean the tomatoes and rocket. Cut half of the rocket smaller. Heat the oil in a pot and sauté the shallot and garlic.
Add rice and stir-fry for about 2 minutes. Deglaze with wine and let it boil down. Add some of the stock. Pour in more little by little, stirring several times and cook for about 25 minutes.

Slice the parmesan and sprinkle with the remaining rocket.
