  • 1 cup baby spinach
  • 1 cup chopped English cucumber
  • Juice of 1 lemon
  • 1 tablespoon ground flax seed

  • ice (optional)


  • Add all the ingredients to a high speed blender and blend on high until very smooth.


This sour apple smoothie was inspired by Kelly LeVeque’s Fab Four Smoothie formula.
For a thicker smoothie use frozen cucumber & apple, or add ice.
To keep this recipe vegan friendly, be sure to use a plant-based.
For a paleo smoothie, be sure to use a grain-free and dairy-free protein powder.
Raw cashews add a creaminess to this smoothie, but to make this nut-free try full-fat, unsweetened coconut milk in place of the cashews and water.
Nutrition & protein information will depend on the type of protein powder you use.
