I didn't believe it so I had to try it. I have seen smoothie and shake recipes with spinach in them and how you couldn't tell that it was in it so here is my experiment.
I added spinch to
1 scoop Chocolate Shakeology
water
ice
1 tsp of PB2
Now to taste.... I couldn't tell that there was spinach in it. I am open to lots of new things but the real test is the husband and the kids.... I gave them all a taste and they all reported.. TASTES LIKE A PEANUT BUTTER CUP.
