Place all ingredients into a blender. Blend until smooth.
1 frozen banana, 1 cup frozen cauliflower, ½ cup black beans, 1-2 medjool dates, 1 cup oat milk, 1 tablespoon hemp seeds, 1 tablespoon cocoa powder, 1 teaspoon ground cinnamon
Pour into a glass and sprinkle hemp seeds over the top if desired. Serve immediately.
Notes
Using 2 dates makes this smoothie very sweet. I prefer just one, but if you're accustomed to a sweeter drink or your banana isn't very sweet, you can go for two.
It's really important that you choose either store-bought frozen cauliflower, or cauliflower that has been blanched and then frozen. Raw cauliflower tossed into the freezer will end up giving the smoothie a very bitter taste.
You can't taste the black beans, I promise!
This makes one LARGE smoothie for a hungry person, or two smaller snack-sized smoothies.
