  • High-Speed Blender


  • 1 cup unsweetened almond milk
  • 1 zucchini frozen
  • 1 cup blackberries frozen or fresh
  • 1 tablespoon chia seeds
  • 1 mini cucumber
  • ½ lemon squeezed
  • 1 handful spinach
  • ½ avocado
  • ½ cup Greek yogurt plain


  • Place all the ingredients together in a high-speed blender.
  • Blend for 1-2 minutes until all the ingredients are combined and smooth.
  • Taste the smoothie. If the mixture is too thin add ice and more milk if the mixture is too thick. Feel free to add a sweetener of choice if it’s not sweet enough.
  • Pour smoothie into a cup and enjoy immediately. You may store the smoothie in the fridge for up to 24 hours.


To make smoothie thicker: Add ice, or frozen raspberries instead of fresh ones.
To make smoothie thinner: Add small amounts of water, or milk.
To sweeten smoothie: Add a banana instead of a zucchini. Please note that this will increase the carbohydrate content.
Feel free to substitute a scoop of protein powder instead of the Greek yogurt.
