Filling your cart with fruits and vegetables is crucial for a nutrient-rich diet. Costco offers an array of options, and its frozen produce section is especially valuable for those concerned about spoilage.

5. Focus on Versatile Ingredients: Items like quinoa, olive oil, and plain Greek yogurt can be used in numerous ways, from breakfasts to dinners, maximizing their value.
