I've been a Costco member for 15 years. Here are 7 items I always buy for my household of 2.

I think the Tyson rotisserie chicken-breast strips and Motor City Pizza Co. pizzas are two of the best things to buy at Costco.

As a Costco member of 15 years, my needs have definitely changed over time.When my kids lived at home, I prioritized buying snacks in bulk. But now that I'm an empty-nester living with my partner, I focus more on nutritious, protein-rich foods that we both enjoy.So, every two weeks, we drive 30 minutes to shop at Costco for our household of two. Here are seven items we always buy.

Plain Greek yogurt is a versatile staple in my fridge.

Kirkland Signature plain nonfat Greek yogurt can be used as a substitute for sour cream or mayonnaise.
