You will need:
3 to 4 ice cubes
Fresh produce — Mix and match to find your favorite combination:
Seeds — Choose one type or a combination; 2 tablespoons total for a single smoothie usually does the trick:
Sweetener, to taste (optional):
Water or coconut water
Combine ice cubes, greens, fruit, seeds and sweetener (if using) in a blender. Cover at least halfway with cold water or coconut water (the quantity will depend on how thick you want your smoothie), then blitz until all ingredients are combined and pureed.
