I froze cabbage last year,and are not impressed with it,how ever,the red one was not to bad,i would only freeze the red again,i used the green one up in stir fries and stews,i only froze it because they all came at once,i also found ,to cook it,it was better to steam it straight from the freezer,all i did was slice it up,wash,shake dry,and bag,you could experiment,prepare a small amount,freeze,leave a day or two,and use,then you can make up your own mind,saves wasting veg,and freezer room.hope this helps
