Bring approx. 4 l salted water (approx. 1 teaspoon salt per litre) to the boil. In the meantime peel and chop the onion. Wash and halve the tomatoes. Clean, wash, drain and roughly cut the rocket. Wash basil, shake dry, cut leaves into strips.
Add pasta to boiling salted water and cook according to package instructions.
Heat the oil in a pot. Sauté the onion in it. Deglaze with wine and cream, bring to the boil. Simmer for about 5 minutes. Dice gorgonzola roughly and melt in the sauce. Heat the tomatoes in the sauce. Season to taste with pepper and a little salt.
Drain the pasta and mix it in a pot with sauce, rocket and basil. Serve with parmesan cheese.
