I still drink a lot of smoothies 8) Here's one from my real experimenting days lol.
Ingredients: left over boiled beet, frozen banana + kiwi, an avocado, some baby spinach and orange juice.
She's a real beaut! It tasted okay. A bit unusual but not bad at all. It was really creamy because of the avocado. And of course the beet gives it this cool color :)
