What fruit is the commonest in the world but also very fast to eat?

Bananas.

Explanation:

According to many sources, the most consumed fruit would be tomatoes, but since people don't go about eating tomatoes, I would go for the second option, which are bananas.

Bananas are really fast to eat (some can be eaten in only 3 bites) and they are the #1 most consumed fruit in the US, and the #2 most consumed fruit in the world, following tomatoes.

Hope it helped,
