I'm an American southerner so I can turn any leftovers into a casserole or a soup. It's in our DNA down here because we don't want to waste food.
So, last night I oven roasted a whole head of cabbage, cut down the middle into two pieces, and put them on a roasting pan cut side facing up. I liberally covered the tops (the cut sides) with a sauteed mixture of fresh jalapenos, onions, tomatoes, garlic, bacon and olive oil. Then I roasted them at 300 degrees for three hours and they were still hard as rocks although they tasted good.
So, this morning, I cut them up into small pieces and dumped them in a crock pot/slow cooker with plenty of homemade chicken stock and pork stock and tossed in a rind of Parmesan cheese. I'll let them cook in the liquid for as long as it takes to soften them up, then blend the mixture into a soup.
I'll like it but can't speak for hubby who is not a fan of cabbage regardless of how I cook it. I'll make a salad for him tonight while I enjoy my soup.
