Mango Yogurt Smoothie. With the weather being so hot and the current situation, it's better to make things yourself when you can. The ingredients are easy to find and not complicated. To choose the right mango for the smoothie, pick one that's slightly sour, which means it's not overly ripe and still has a hint of green. If you use a very ripe mango, it will be too sweet (personally, I don't like it too sweet) and lack other flavors.
