In fact, the #avocadotoast has more than 1.2 million posts on Instagram which is 1.1 million more than me. Who said that? Because I post all the time. This begs the question, how did avocado toast become a thing? One key to the avocado toast phenomenon is that young people love avocados. Avocado! Thanks! And young people are part of what's known as a desirable demographic because they spend money, and avocado toast can cost a lot of money at a restaurant, oftentimes north of $20, which makes sense because of how complicated it is to make with ingredients such as avocado and toast.
