I love this creamy smoothie. Sharp and tangy yet the addition of avocado gives it a wonderful luxury feel and smooth texture. I use coconut kefir but you could also use coconut cream or milk instead. Use a full fat milk for a lovely rich flavour. You will need to add a little sweetener. To keep the glycemic index low choose xylitol or stevia to taste. Cram in a few fresh greens as well for a detox boost and perhaps a spoonful of superfood green powder.
