Forgive me for posting another kefir smoothie recipe, but this is too delicious not to share! I love the simplicity of the flavours here – and what a great purple colour. I like to drink this as a post-parkrun refuel.

If you don’t have any kefir, try using a combination of plain yogurt and milk to replicate the tanginess of the kefir. I added two tablespoons of Rude Health Smoothie Oats and one tablespoon of ground flaxseed for a nutritional boost; I’ve also tried this smoothie with a spoonful of maca powder (delicious!) and some protein powder. Jazz up your smoothie however you like, or keep it simple with just the banana, blueberries and dairy!
