I also use a smoothie to add more protein . The protein powder is whey-free , called, " Jay Robb's protein powder,in flavors of plain, strawberry or chocolate,
This powder can be mixed with water or milk or another beverage.; to keep lactose- free, I use Soy milk, vanilla, 1 cup, or 1 cup Greek yogurt, plus I add fresh fruit that is soft,ripe, either, half of a banana,and 5 strawberries ( stem removed), Or a soft green pear, skin removed, and a kiwee fruit, to sweeten, I use either a packet of Stevia sugar, or a Tablespoon of honey.
I recently read on Pintrest, to add a couple of Tablespoons of Oatmeal to the Smooothie right before blending.
