So far I've only been having chocolate shakes on my diet, since fake vanilla has never really worked for me. And I do like chocolate. But having 3 shakes a day starts to get old pretty quick, so we're given all sorts of suggestions on things we can add to the shakes that are still "in the box" - meaning that they're safe for us to use. I've tried some of the sugar-free Torani syrups and they're just not really working for me combined with the chocolate.
However we've got a new seasoning "in the box" and it's crazygood:
Yeah, that's right, powdered peanut butter. It's way lower in fat and calories than "regular" peanut butter. 1 serving is 2 tablespoons and is 45 calories. However, I have found that only 2 teaspoons are necessary to turn a somewhat bland HMR shake into a frozen peanut butter cup. I'm only using it once a day right now to avoid burning out on it, but if you like peanut butter (and I am rather fond of it) I bet there's all sorts of things you could do with this stuff.
