Ever since green smoothies burst onto the scene in the 1990s, these endlessly customizable blends of fresh produce and other mix-ins have become an indispensable weapon in the healthy person’s arsenal. Simply start with a couple of handfuls of your favorite leafy green, toss in a few pieces of juicy fruit (berries and citrus work best because of their intense flavor and high water content), and blend in your liquid of choice until the smoothie reaches the desired consistency, and viola! You’ve got a nutrient-packed, portable snack, breakfast, or post-workout treat.

My favorite blend below adds a touch of the tropics with a blend of tangy pineapple, creamy banana, immune-boosting orange, and ultra-hydrating coconut water, while spinach offers a neutral base teeming with vitamins A, C, and K. Make it more substantial with the satisfying crunch of your favorite granola and fiber-rich chia seeds, or swap the coconut water for a dollop of Greek yogurt for additional protein.

If the ingredient list is making your bank account nervous, here are a few ways to keep your smoothie spending under control:

Stick with the seasons: Citrus season is still in full swing, so now’s the time to add a sunny burst of vitamin C to your smoothie. Experiment with Earth Fare’s broad range of orange varieties including Sumos, mandarins, and valencia!

Frozen is just fine: Smoothies are a great way to use up fresh produce before it goes bad, but frozen fruit packs the same nutritional punch and is easier on your grocery bill. You may want to adjust the amount of liquid you add, as frozen fruit adds more liquid as it’s blended.

Buy in bulk: Mix-ins including granola and chia seeds can add up fast. Shop Earth Fare’s bulk section for lower prices on over 150 varieties of seeds, grains, and granolas, all without artificial sweeteners, colors, or flavors.
