This sour green apple smoothie is a deliciously tart and surprisingly refreshing beverage. This tangy smoothie is packed with fresh apple and dairy-free yogurt for a zesty punch.
Slice the apple and banana and place them in a blender. Add the protein powder, yogurt, and spinach to the blender. Blend on low until broken down. Scrape down the sides of the blender jar and blend again, gradually increasing speed until smooth.
Add 1 cup of ice and blend on low until most broken down. Gradually increase speed until it gets smooth.
Take a taste test. If you're happy with the consistency, coldness, and sweetness, then you're done. To make it thicker, add a second cup of ice and blend on low, gradually increasing speed to make it smooth. To make it sweeter, add a bit more protein powder or some maple syrup.
Pour the smoothie into glasses and enjoy!
