"Mass-produced avocados are very, very harmful to the environment they are grown in. I am from Chile and avocado trees are literally leaving people without water to drink or use in their own farming zones. Petorca (the town that suffers the most from overly-produced avocados) is literally dried out by these super-thirsty vegetables. I'm glad Americans are becoming more and more aware of how damaging avocados are." - Youtuber (paraphrased)
How to substitute them: in a food processor mix chic peas, green peas, onion powder, sage, tarragon, rosemary, parsley, salt, cooking oil, nutritional yeast, and lemon juice or extract. You're welcome.
