Avocado toast is a type of open sandwich consisting of toast with mashed
avocado, and usually salt, black pepper, and sometimes citrus juice.
Ingredients added to enhance the flavor include olive oil, hummus, red
pepper flakes, feta, dukkah and tomato.
Avocado toast became a food trend of the 2010s. It has appeared on café
menus since at least the 1990s. Following avocado toast's elevation to
trend status, the act of ordering avocado toast at a café was criticised
as a symbol of frivolous spending.
