I have never tried another other veggie. It's worth a try tho. That's what I did with the spinach, and it was good. Let me know if you try them.
I'm not an expert on powders. I just know I have plenty of bad experience with them. The 2 I use now is Revolutionary Technology Bionic Whey Chocolate it no chemicals or artificial sweeteners(my fav) I want to try their other flavors too. It was on back order so I tried Gold Standard Whey chocolate and I like it! But I will most likely go back to the Bionic whey when I run out of the Gold Standard, but it's a good back up one.
