Talk about a super charged meal in a glass! I use hemp hearts as the major protein source for this drink. In addition to being a complete protein source, hemp hearts also contain the ideal balance of omega 3-6-9 fatty acids and are high in fibre. They work wonderfully to make this smoothie super creamy, all without needing any banana. This smoothie also highlights one of my biggest cravings - the juicy red grapefruit - which is balanced with a sweet apple and buttery mango. If you prefer a sweeter smoothie, feel free to swap the grapefruit juice for coconut water or orange juice, or add a touch of liquid sweetener.
