Some people just mix it with milk, like a yogurt smoothie..
I actually put it in the blender, with ice and water (again, some people use milk, I choose not to use points doing so---I'm not a huge milk fan), and then add whatever I want. I have created all kinds of combos--I will sometimes throw in fruit, other times WW yogurt, other times things like pumpkin or applesauce. A lady in my WW group said she will put the smoothie mix with WW mini bars, 100 calorie packs, or Fiber1 bars for a milkshake taste. Be creative!
My personal fave: mix ice, water, WW vanilla smoothie mix, 1 WW ice cream latte bar, and some Walden Farms 0 calorie caramel. YUMMY!
