Cut the romanesco into florets and add to boiling water with the vegetable stock and cook for about 12 minutes.
Then lift out the florets with a slotted spoon and place in a non-stick casserole dish. Add some of the vegetable stock and season with pepper. Spread the grated cheese and parmesan on the cabbage. Bake at 200 ° C fan oven on the middle rack until the cheese is lightly brown.
You can now eat the cabbage with baguette or serve as a vegetable side dish.
