This is fast food, and it's real good food too. If you've never had a portobello burger before, your world is about to change. Throw whatever else you want on these bad boys, I know that fresh tomatoes would be epic, as well as some red onion. The textures in this recipe are soooo perfect for each other. You've got the meaty mushroom, the creamy guac, the fresh greens AND the amazing crunchy, savoury, heavenly Hippie Garden Chips.

  2. To make the guacamole: mash the avocado flesh with the lime juice, salt, pepper and chili (if using). Adjust according to taste. Some garlic might be nice.
  3. Take a mushroom top and spread on some guacamole, then pile with greens and tomatoes. Drizzle in a little tahini if you like, then wrap up in a collard leaf!

  1. Just wondering how this can be considered raw when the mushrooms have to sit in the oven for a half hour. It sounds delicious and I can\’t wait to try it but call it what it is: a cooked bunless portobello burger.

    1. Hi Tina! Thanks so much for replying and checking out this recipe. It\’s actually considered raw! A raw food diet consists of foods which have not been heated above a certain temperature. The maximum temperature for raw foods is generally accepted at 118 degrees Fahrenheit. Of course, this varies based on the person\’s preference! Dehydrators work at this temperature. I hope this helps you and I hope you try to make this burger! :-) – Ally, recipe coordinator
