Whether a green banana is considered a vegetable depends on how it is being used.
While botanically a fruit, green bananas are often culinarily treated as a vegetable due to their starchy, less sweet flavor and common preparation methods. In many cuisines, particularly in the Caribbean, green bananas are cooked in savory dishes rather than eaten raw as a sweet fruit.
Therefore, the answer is: It depends on the context. It's a fruit that is often used as a vegetable.
