PB2, Powdered Peanut Butter, 7.49 Amazon add-on item
Picked some of this up on the last time it was about this much. Great product. This is for the 1 pound bag.
Basically its low calorie peanut flour. Mix with water and it tastes pretty much like peanut butter. Also good for shakes and cooking.
Edit: Just noticed the PB2 + Chocolate is 16.06 for two 16 ounce packages. Free Shipping with Prime. I might try some of that too, not sure I want to jump right on two pounds of it though.
Double Edit: 2 lbs. Regular PB2 is 16 with regular Prime shipping. no need for add on program.
