Pea protein is the new ingredient that is added to protein powder and smoothies, I'm just realizing. Am I late to the game? I feel like I always overlook peas as being boring or something I used to be made to eat as a kid but they are actually pretty awesome. I bought frozen peas yesterday at Whole Foods so I could make a smoothie today and I wasn't disappointed. To make the sweetest smoothie with bananas, make sure you use super ripe, speckled bananas, as ripe as you can possibly buy. The riper the banana, the sweeter the ice cream.
