Love all of them but the plain hot chocolate mix is probably my favourite.  Sometimes I add more hot water than is called for to make a bigger drink.  I do it more often in the cold months when I want a big hot drink.  I also add a touch of milk or cream sometimes and a package of no calorie sweetener sometimes.  Hot chocolate in the evenings in the cold months is my favourite drink and to have one that's high protein, low carbs, is fantastic.
