I always weigh my vegetables raw and then cook them. Once they're cooked into a soup I can't take them back out to weigh each vegetable very easily. lol At least I imagine that would make a big mess with broth everywhere.
I like the taste of raw cauliflower and cabbage but I can't eat it anymore or at least I feel I should cut back on that, because I was told I have subclinical hypothryroidism so I read that I should avoid raw goitrogenic vegetables. It's a shame because when I was cooking them I'd eat some raw and some cooked and that was fun.
