I created this as a healthy afternoon snack to hold elena through until supper, but some way or another it ended up as my work day breakfast shake. It holds me through most of a shift quite nicely.

1 banana ( 2 if they are small)
2 Tbsp. peanut butter
3 Tbsp. flavored (your choice--chocolate is our favorite) protein powder (soy or whey)
10 oz milk

Throw all together and mix well with a blender.
Amounts can be varied to suit your taste.
