Doubt you're getting much from vegetables
(Are beans and such considered vegetables?)
I used to also get Kaizen Protein at costco (35$ or so for 4.4 lbs when on sale) and then
I tried a little bit more expensive proteins (26$ for 2 lbs in this case) and the difference (taste and texture) is night and day when mixed with water or almond milk. In a smoothie with bananas and other, I could not tell the difference at all, so depending on how you would consume it.
Bulk Barn was mentioned above: It's much more expensive there, and you can't really tell the Brand or profile of it, would not recommand
