I have come up with the best tasting shake that I make using a Magic Bullet blender...and it good for you.
Ice (A few cubes)
1 Diet Swiss Miss packet
2T PB2 Powder
1/4 C Plain Oatmeal (Instant,quick cook or old fashion)
1 Banana (cut up to fit in cup)
Skim Milk (Fill to top of bullet cup)
Blend well using your magic bullet or use a blender. Love it!!!
