So far I am thinking:
Cabbage soup (an absolute favorite of mine)
Boiled cabbage (side)
Stuffed cabbage rolls
Fried cabbage with pork
Cabbage and noodles
Homemade sauerkraut (gonna start fermenting it on day 1) (side)
Vinegar coleslaw with NO SUGAR OR SWEETENER (side)
What should I do for the rest?
Probably some cabbage-based salads you could do that are creative. Reuben sandwich
Good thing this isn't a broccoli challenge, there would be like 3 things here!
