This Vanilla Avocado Greens smoothie has been a hit in my house since my kids were young. Avocado adds all the decadent creaminess you’re used to having in a milkshakes, only it’s obviously a great deal healthier than using ice cream. It’s no wonder this superfood is often nicknamed “vegan butter”. You get all the luscious texture and rich flavor without any of the the refined sugar and heavy cream.
