Add all the ingredients to a high speed blender. Blend until smooth.
Notes
Protein Powder: Since the sweetness from this recipe comes from the protein powder, be sure to use a brand you enjoy the taste of!
Frozen Cauliflower Rice: No, you can't taste the cauliflower rice in this smoothie and it adds creaminess without needing any banana. Be sure to use frozen riced cauliflower.
