My preparation is even easier then yours, I can't stand cooked veggies so I eat them all raw. But I do prepare them all for the week in advance. My Sunday night includes washing and cutting my broccoli, cauliflower, celery, and carrots and then packaging them in five quart size ziplock bags so I can grab a bag and go. I eat raw spinach in my morning shake. Evenings I usually eat a salad.
Unfortunately I still am paranoid that I am not getting enough veggies, and I know my kids aren't. So if I can give them a drink in the evening to help it along, or through some in their apple juice, then I can sleep at night.
I looked at greens plus, but they have stuff like soy, corn and wheat in them which my wife can't have.
The Berry Green from New Chapter looks like some good stuff. Going to go ahead and order some of this and give it a try.
Thanks for the replies.
