Sugar Free Syrups
That's an awesome price, Erika! Those syrups saved me many a time at the beginning and they are just as good as the more expensive DAVINCI syrups. I'd buy big jugs of vanilla protein and then make ANY flavor I wanted out of it with the syrups.
Another good "flavor boost" ...are the EXTRACTS that you can find in the baking aisle. Food Lion has a really BIG selection (so does the commissary if you have access to the base?) ....but a couple of drops with some splenda and you have a flavored drink. Pretty cost effective and lots and lots of flavors to choose from.
I'm pretty set in my (boring) ways now and I just do the vanilla protein mixed in some iced coffee - but I still have some of the extracts in my cabinet - who knows, I might get all domesticated some day and wanna {gasp} ....BAKE?
