I live in California and have an avocado tree. Guacamole, on sandwiches, or just slice them with pepper and salt. Have no idea what avocado toast is. Lol
When we lived in Hayward, CA, we had a huge avocado tree but would only get a couple avocados from it. I think it might because there were no others to pollinate it. Fwiw, I like avocados. I never had them until I moved to CA.
