I have quite a few friends on the Keto diet. If you're not familiar, it's basically low carb/high fat, and no sugar. No sugar means no milk and no fruit.
Basically, it's a way to get Starbucks' Pink Drink, but Keto-friendly.
You'll need to ask your barista for passion tango tea with sugar-free vanilla syrup, heavy or light creamer, and Splenda (optional). In regards to taste, an Instagrammer (@andlookhowfarivecome) has said, "it almost tastes like the [Starbucks] strawberries and cream frappuccino."
Enjoy!
