Wash the pak choi, clean and cut into approx. 7 mm strips; separate the white stems and green leaves.
First sweat the cut white stalks, garlic, chilli pepper, onion and ham in a little olive oil, then after about 4 minutes add the cut leaves and sweat them briefly.
Pour in the broth and cream, season with salt and pepper and simmer for about 5 minutes.
If you like, you can thicken the sauce with a little flour butter.
