Make sure you use a high powered blender, as the kale is quite tough. If you don't have a high powered blender, then blend the kale with the almond milk first and then add the rest of the ingredients and continue blending.
You can use any milk you like in this recipe.
If you want a banana free smoothie, swap it for half an avocado.
Remove the ribs and stems of the kale before adding it to the blender.
Give the smoothie a stir before serving, as it can get a bit mottled.
You can save yourself some time and make it the night before and store in an air tight container.
Make a super cool smoothie by freezing the banana before using it.
You can swap the kale for spinach or use a mixture of the two.
Adding a little bit of lemon really gives it a lift.
If you wanted to make it even sweeter (not that we think it needs it), then you could add a little bit of orange juice to it.
Make it even cooler by serving it over ice.
If you need even more of a pick me up from your smoothie, add some grated ginger to it. Only a little though, as a little goes a long way.
