Measurements are guestimates:

2 cups of low fat plain yogurt
1 cup of pumpkin-Libby's
2 cups of filtered water
Ice cubes
Blend until smooth

You can throw ice cubes in to make this smoother and creamier if you want.  To make it more substantial I threw in some cooked oatmeal and just ground that up, too.

I just throw stuff together in my kitchen and never measure anything except Toby's meds!
