Favorite 4 Ingredient Green Smoothie

Just like most of you, it is time for me to focus the new years resolutions I made. Eating healthier is usually one of them, which my favorite 4 Ingredient Green Smoothie Recipe helps with. Bonus, this smoothie is crazy delicious!!

If you are not a green smoothie person, I think this simple recipe will win you over. Pinky swear!! I waited years and years before I got over my mental paralysis at the thought of a sip of a green smoothie.

Once I finally gave a smoothie with spinach a chance (thanks to my tween daughter), I became obsessed! This easy smoothie recipe is so fresh and vibrant. It's a boost both mentally and physically for me every time I make it.

When it comes to a green smoothie, sure its green but honestly, you do not taste the spinach at all! Yet you get the benefits of vitamins A & K, potassium, beta carotene and more.

Ingredients

• 1 Apple (leave skin on) I like Honeycrisp (use whichever apple you enjoy)
• Big handful of spinach (about 3 ounces/1 packed cup)
• 1 banana (the more ripe the banana sweeter it will be)
• 1 heaping cup frozen mango (see notes)

Green Smoothie Variations

• Swap the spinach for arugula or watercress for (both alternatives are nutrient dense foods)
• Add in fresh or frozen pineapple
• For a hint of heat and additional health benefits add a little fresh ginger
• Add in a squeeze of lemon or lime 
• If you want it sweeter, add in a drizzle of honey
• Swap water for coconut water

This super easy 4 Ingredient Green Smoothie can be made in minutes!

I make it at least 4 times a week, typically for my first meal of the day or for a snack. Or I crave something sweet in the evening like candy or cookies, I will whip up a healthy smoothie instead. THIS satisfies my sweet craving and bonus it gives me nutrients and antioxidants that a candy bar can't.

Tips

• Using frozen mango is what makes this smoothie so smooth and refreshing. If you want to use fresh mango, cut it up and freeze it first.
• Adding ice isn't the same as frozen mango chunks, you end up with ice bits with no added flavor, so don't do that.
• Stay close to the recipe or follow the variation suggestions above.
• Since this is a smoothie made with whole food ingredients, I like to be sure the added water is pure. I happen to have a Big Berkey Water Filtration System (which filers out 99.9% of heavy metals, chlorine, bacteria, pesticides and more from the water I use), making it the healthiest water for my family and I).
• This is SO fresh and bright tasting, if you start adding milk or nut alternatives it may be good however it just won't be this.
• I am all about experimenting. However, if you want a green smoothie that is easy to make with a consistency that I think you will enjoy with the boost of nutrients and antioxidants found on these ingredients, this is it! Bet your kids will enjoy this as well.

If you are looking to kick off a few weeks of healthy eating or a doing a natural food detox, check out my Tomato Detox Soup. It's a favorite of many. I always use this soup to drop 5-7 pounds when I need to.

Or my Pumpkin Detox Soup, its bursting with health benefits! AND you may be very surprised at how delicious it is.

I hope you love this spinach apple smoothie recipe as much as my kids and I do! XO Colleen
