- Place all the ingredients except the lime zest in a liquidiser and blend until smooth.
- Pour into a tall glass and top with a little grated lime zest, if using.
Smoothies made with fresh banana don’t keep too well as they discolour, so it’s better to make just the quantity you need. Try using 100g strawberries, raspberries, blueberries, blackberries, mangoes or nectarines, or a combination of these, instead of the banana. If you have a dairy allergy, use soya-based products.
