You can use it the same way as any other cabbage of this type (Savoy, Greyhound).
My dh likes this recipe:
Sausage in a Nest of Cabbage
1 Savoy or Hispi cabbage
1 clove garlic, finely chopped
1 sprig fresh rosemary or 1tbsp dried
1 tsp vegetable oil
8 good sausages (Cumberland, Lincolnshire etc)
8 fl oz beef or chicken stock
3 tablespoons red wine
Melt butter in a frying pan, saute the cabbage, rosemary and garlic oer a medium heat for 5 minutes, Remove from pan, set aside.
Wipe pan, add the oil and heat. Fry sauages until browned (or grill while the cabbage is cooking).
Remove the sausages from the pan, pour off excess fat. Return cabbage to pan, bury sausages in it. Add the stock, wine, salt and pepper, and scrape the bottom of the pan to loosen any browning. Cover the pan and cook over a medium heat for 20 minutes, moistening the cabbage with more stock if necessary.
