It is amaaaazing. Seriously I love peanut butter and this is a guilt free way to enjoy it. I started having 1 tbsp (half a serving) at night after dinner in P3 as a treat. Its so good!
Had it this AM on toast, again it tastes like the real thing. I don't like super sweet PB so maybe I am a little different, but it taste like real peanut.
Another great snack I found for P3 & P4 snacking: Almond milk heated up with a splenda pack. You can get the unsweetened vanilla kind and it is delicious. 35 calories 1 gram of sugar.
