Cook the pasta in salted water according to the instructions on the packet. Meanwhile, cut the bell pepper and onion into small cubes and fry in the butter. When the onions are translucent, add the tomato paste and roast, then add the cream cheese and then deglaze with the milk. Add the spices and simmer for 5 minutes.
Drain the pasta, add to the pan and simmer for another 2 - 3 minutes. Shortly before the end, cut the tomato into small cubes and add so that it is heated but does not lose its bite.
Of course, other vegetables or other vegetables can also be used. Parmesan also tastes good with it.
