Combine mulberries (if using), vanilla, sunflower seed butter, and water. Blend to combine. Add frozen cherries and blend. (If you have a high speed blender like a vitamix, just dump everything in and blend it)
Add desired amount of ice to thicken. Serve immediately!
Notes
Milk will yield a creamier smoothie. I like to use oat milk or hemp seed milk.
Add more ice to thicken the smoothie (or frozen fruit) and more water or milk to thin it. Max out at 1/2 cup of ice or it may water down the smoothie.
Use seed or rice protein powder or hemp seeds to boost the protein content.
Mulberries can be substituted for 1/2 a frozen banana, however this is not migraine diet friendly and has a higher sugar content.
Feel free to add 1 tablespoon of goji berries to the mix!
