It is in a steam bag, allegedly has 3 servings of 2 cup size, but I measured the entire bag after cooking, and it was 2 cups. I suppose if one fluffed it a bit, it might be more
I just figured eating the one cup was 1.5 of the nutritional values listed re carbs/calories.

It has, being Kohlrabi, a slightly sweet taste - if that is off putting, I'd try a bit of marinara sauce or a lemon juice/butter/fresh herb sauce.
