Are smoothies a healthy meal replacement?

I generally have smoothies for breakfast. I don’t consider it a meal replacement, I consider it a meal.

My smoothies never have milk in it, unless it is almond milk. It almost always has at least one banana added and other fruit–like berries, dates, peaches, nectarines melon or orange juice. During the winter I use winter fruits. For me it is a delicious, satisfying breakfast.
