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

"I love to stock up on nutritious jarred items like hearts of palm. Hearts of palm are great when eaten whole, like string cheese, or chopped up in salads. They can get expensive if you buy the small ones, but you get a great deal when you buy them in bulk. Sometimes I open and drain a jar and drizzle balsamic vinegar over them. It's a quick, filling snack that's under 80 calories and mostly fiber." — Ilana Muhlstein
