Green Monster Smoothie! There’s no right or wrong way to make a green smoothie, but this one has a large volume of greens, creating a monstrous green colour! The raw kale adds important anti-cancer phytonutrients. The linseeds boost the omega-3 content, add fibre and help thicken the drink. In order to obtain a super smooth and silky drink, I recommend a high speed blender e.g. Vitamix.
