Dietitians Spilled Their Favorite Costco Foods and Basically Rewrote My Grocery List

"I always purchase large containers of nonfat Greek yogurt to keep handy in the back of the fridge and to make my 'Wonder Whips.' Those containers sometimes last a month because they are lower in water content and more concentrated in protein. For my (guilt-free) Wonder Whips, I simply mix the yogurt with a splash of almond milk, stevia, cinnamon, and coconut extract for a yummy, quick, and healthy dessert." — Ilana Muhlstein
