Cook the tortellini in simmering salted water according to the instructions on the packet. Then drain in a sieve.
In the same saucepan, sauté the onions, ham and garlic, season with salt, paprika powder and pepper (possibly also herbs) and the broth. Then pour in the cream and add the tomato paste. If the consistency is too thick for you, you can add milk if you feel like it.
Stir in grated cheese (I myself like to use Edam, but Camembert or Emmentaler are also suitable for this) and simmer until it has melted and the sauce has a pleasant consistency. Add the tortellini, mix everything, bring to the boil again briefly and serve.
