Wash the apple and cut it into pieces, peel the carrot and cut it as well. Peel and dice the beet, squeeze the lemon.
Blend all ingredients in a stand mixer (alternatively with a hand blender) until a velvety mass is formed. Add a little water or more lemon juice if needed.
Pour the smoothie into a glass and serve.
Preparation Tip:
The beet smoothie becomes a filling breakfast when you add bananas and chia seeds.
