Cut eggplant into ½ inch thick half-moons or into bite-sized pieces. Place in a big bowl covered with water and stir in salt. Cover with a plate and let stand for 20-30 minutes.
In the meantime, chop the garlic and ginger and make the Szechuan sauce.
Drain eggplant and pat dry. Coat with olive oil. Put the eggplant in the air fryer basket.
Air fry the eggplant at 375 degrees F for 20 minutes, shaking the basket halfway through.
Add 1 more tablespoon oil to the skiller, and over medium heat, add the garlic and ginger, stirring for 2 minutes. Turn the fan on, add the dried chilis and stir for one minute. Pour the Szechuan sauce into the pan and bring to a simmer for 20 seconds. Add the eggplant back into the skillet, tossing gently for about 1 minute. If it seems dry, add a tablespoon of water to loosen.
Serve with brown rice (optional).
