It is absolutely essential that you use Greek yogurt instead of regular yogurt because of the high water content of the melon and cucumber. It still will probably be a little less thick than your average smoothie, but very delicious.
Here’s what you need for two servings (about 24 oz. of smoothie):
Seed and cut the cucumber and melon into 1-inch cubes.
Add the yogurt and juices to the blender first, followed by the fruit, followed by the ice. Pulse until smooth, and refuel away!
