Avocado toast is an open sandwich consisting of toasted bread topped with mashed avocado, plus any of a variety of spices and flavorful ingredients; the most popular include salt and black pepper, lemon juice or other citrus flavors, olive oil, hummus, vinegar, red pepper, feta, duqqa and tomato.
Avocado toast became a food trend in the 2010s; however, the preparation has appeared on café menus since at least the 1990s. There have been several debates about where the dish first appeared on menus. Following avocado toast's elevation to trend status, the act of ordering avocado toast at a café was criticized as a symbol of frivolous spending,[1] along with the environmental impact of shipping the fruit from subtropical growing regions.
