Clean mushrooms under slowly running water. Gently rub to remove dirt from mushroom caps.

Put mushrooms in a small bowl. Add the coconut aminos, oil, and garlic salt.

Gently move bowl side to side to help coat the mushrooms with the mixture. Add mushrooms to air fryer basket, with the bottom of the mushroom facing up. Cook mushroom caps for about 9 to 11 minutes at 350 degrees F or 180 degrees C. Flip caps with about 2 minutes remaining in the cook time.

Remove mushrooms from the air fryer and let stand at least 2 minutes before slicing into long pieces. Divide mushrooms between tortilla shells and add your favorite toppings. Enjoy!
