Peanut butter Milk Shake (p1)

When on South beach P1 you are to drink 2 glasses of milk and or have some yogurt for your dairy. Sometimes for a little added treat, that's not counted as a desert I make this:
Peanut butter Milk Shake
(2 servings)
1 1/2 to 2 cups of skim milk
1 to 2 T splenda 2 to 4 T natural peanut butter (crunchy or smooth)
a little ice
sometimes I add a splash of vanilla extract and or
a little sf Hershey chocolate syrup.

Mix this all up in a blender and Enjoy!
Depending on how much milk and Pb you use, this will count towards one of your milks and your nut allowance for the day.

Note: Don't add too much ice as the texture is a bit funky. You want it more milky thank icy.
