Layer all ingredients into a blender, starting with the apple and fennel, ending with the yoghurt and oat milk.
Blend on high until the mixture is completely smooth.
Pour into a glass, and serve immediately.
Notes
*I use frozen spinach in my smoothies, which is why this looks more pink than green. Where I live frozen spinach comes in small cubes, so I just toss a handful in to the blender. If you’re using fresh spinach, use 1-2 cups and anticipate a much greener colour.*Do fennel and apple really blend up smooth? I have a powerful high-speed blender and so far there’s nothing I’ve thrown at it that it couldn’t handle, including carrots, apples, fennel, and celery. If your blender isn’t so powerful you might want to err on the side of caution and chop or grate your apple and fennel before blending.*Want extra protein? A tablespoon or two of hemp seeds is mighty nice here.*Lastly a note on quantity. I like to drink a large smoothie, and right after I took these photos I drank both of those glasses. If you’re not super hungry this will probably be enough smoothie for two people, but if you’re hungry, fuelling or recovering from a workout, or just like a lot of smoothie, this serves one.
