Choose your preferred fruit (e.g., half a banana, a few strawberries, half a mango) and vegetable (e.g., a handful of spinach or kale), and wash them thoroughly. Peel and chop the fruit into small pieces.
In a blender, add 100 grams of chopped fruit, 25 grams of vegetables, 75 grams of yogurt or milk, and a couple of ice cubes. You can also add a sweetener like honey or sugar, as per your taste.
Blend the ingredients until you achieve a smooth and creamy consistency. If the smoothie is too thick, add a bit more milk or yogurt to adjust the consistency.
Pour the smoothie into a glass and garnish with a couple of fruit slices or a mint leaf, if desired. Serve immediately.
