A medium sized head of cabbage contains 218 calories, so two heads would be 436. A tablespoon of shortening has 108 calories, and a tablespoon of sugar has 48 calories. That's a total of 592 calories for the whole pot. Do you know how many cups of boiled cabbage you get out of the recipe? I've never boiled cabbage, so I don't know. I only like cabbage in coleslaw
