Homemade green smoothies are a fast, easy and inexpensive way to get fibre, folate, vitamins and antioxidants in your diet. One trick that will make whipping them up not just easier but also more convenient is to freeze some kale cubes ahead of time.
Cooking site Spoon University explains how (and why) to make kale cubes: purée kale (or any other desired leafy green, like spinach) with a little bit of water in a blender, then pour into ice cube trays and freeze. Transfer them to a zip-locked plastic bag and pop a block into your blender anytime you want to add a dose of green to a blended drink.
This not only prevents you from having to worry about washing or chopping kale every time you want a green smoothie, but it also means you don't have to keep fresh leafy greens on hand every time you want a green blended drink. Bonus: The frozen block keeps the smoothie cold, so you won't need to add as much (if any) ice.
