Peel and chop the fruits. I used a mix of mangoes, bananas and sapota (chikoo). You can use other fruits like apple, berries, figs etc.
Add the chopped fruits in a blender jar. Add milk and quick cooking oats. I did not add any sugar. But if you want you can sweeten the smoothie with sugar, jaggery or honey.
Blend till smooth. You can add some ice cubes if you want while blending.
