I'm a big fan of Vega One shakes, they have a vanilla chai shake that's so delish and they're really good for you. Not sure where you are in the world but you can find them online here: http://myvega.com/products/vega-one-shake/features-benefits
Or at health food stores in Canada.
Try to stick to one you buy at a reputable health food store or
Organic store as they tend not to contain genetically modified ingredients
and artificial fillers.
Ps sorry I didn't respond right away! I didn't get a notification about this post lol
Good luck with everything!
