This is actually a healthy smoothie, but I call it a milkshake because it tastes like dessert. The frozen banana makes this drink sweet and richly creamy, while the cacao adds a subtle crunch. This smoothie has 22 g of protein and costs $1.16.
*I use Bob's Red Mill soy protein powder, which I wrote about in a previous post. It's cheap and simple, and I love it.
Just blend everything together!
