I have never had avocado toast, I like avocado the way it is, you know, it's a fruit, so I don't want to mix it with bread or anything else to be honest with you, but yeah, if it's very common, maybe there's a reason for it, maybe it tastes great, maybe I should try it, you know, but yeah, mixing avocado with tomato also doesn't sound very right to me, but I don't know.
