Banana sauce is commonly known as Banana ketchup.

It was actually invented during WWII when tomatoes, and therefore ketchup, was in rare supply.

So people began making their ketchup using bananas instead, which resulted in a sweeter condiment, and it has been widely adopted by Filipino cuisine, to the point that many noodle dishes and other meals require it as a specific ingredient.
