Because not every day can be a fry day.

Trying to build a healthy pantry? The good news: A tasty, nutritious kitchen pantry is only a few steps away — and more affordable than you think. The bad news: It's up to you to actually buy the products and get cooking. Today, toss your excuses to the curb and load up your pantry with these healthy and wallet-friendly staples.

1. Canned beans

Canned beans are an excellent source of protein and fiber and last for around two years or more. Wildly versatile, you can use them to bulk up soups, add to stews, toss in salads, or serve as a side dish.

2. Olives

Unopened jars of olives can last for a few years and are a delicious way to add flavor to an otherwise lackluster salad. Try adding a handful of olives to your next batch of hummus for a briny kick. 

3. Chia seeds

You don't need to go to the trouble to make chia pudding to enjoy these tiny, nutrient-dense seeds. Packed with Omega-3 fatty acids, slip them into a smoothie or into a vinaigrette (you won't even taste a difference). At breakfast, enjoy a spoonful on top of oatmeal or add to your favorite cereal.

4. Vinegar

From apple cider vinegar to balsamic, these flavor-packed potions add nuanced flavor and depth to virtually any meal. They also keep for ages.

5. Extra Virgin Olive Oil

Vinegar's other half is a boon for your health when used in moderation. In a much discussed New York Times Magazine article, olive oil was one of the main diet staples on Ikaria, "The Island Where People Forget to Die." Our favorite? A two-liter bottle of Kirkland Signature Olive Oil retails for $18.99, with a two-tablespoon portion clocking in at 28 cents.

Now, just remember friends, just because these pantry staples last a long time, doesn't mean you have to buy five of each. ;-)
