Cut off the outer leaves of an organic cauliflower and wash thoroughly. Separate the green from the stems. Cut the stalks into strips approx. 1 cm wide and tear off the greens. Process the florets otherwise.
Heat the olive oil in a saucepan and briefly sweat the stems in it. Add the leaves and pour in the water. Add the small leaves of the thyme with a little salt. Put the lid on the saucepan and let the cauliflower simmer for about 15 minutes.
If there is still water in the pot, drain it off. Fold in the pecorino and serve the vegetables directly.
