The last time I went to the Bubble Tea stand in my mall, I kept my container so I could make my own smoothies & bubble teas. To keep this as low-cal as possible, I used less than 1/2 cup of unsweeated vanilla soy milk and then thinned it out with water as I blended it. I added boba in the bottom – making a quick batch by boiling them for 10 min and then running cold water over them to cool them off.
Bon appetite! Enjoy your healthy and filling smoothie.
