Time is always of the essence, which is why Pack’d frozen smoothie mix works a treat. Individual kits of frozen fruit and veg plus a sachet of boosting superfoods such as spirulina, wheat grass or flax, simply need chucking in the blender with your choice of coconut water or apple juice. You’ll be walking out the door, smoothie in hand, in minutes. Just choose from Defence, Detox or Energy. Available from Sainsbury’s.
