Prepare the Sauce: In a small bowl, whisk together the soy sauce, dark soy sauce (or additional soy sauce), vegetarian oyster sauce, rice vinegar and maple syrup until combined. In a separate small bowl, mix together the cornstarch and cold water. Set both aside.
3 tbsp tamari or soy sauce, 1 tbsp dark soy sauce, 3 tbsp vegetarian oyster sauce, 1 tbsp rice vinegar, 1 tbsp maple syrup or coconut sugar, ¼ cup cold water, 2 tsp cornstarch
Cook the Eggplant: Heat 1 tbsp of the oil in a large skillet or wok over medium-high heat. Once it's hot, add the eggplant and toss to coat in the oil. Spread the pieces evenly around the pan in one layer. Sprinkle a little water over the eggplant, cover and cook for 2-3 minutes, flip the pieces and sprinkle with a little more water, cover and cook another 2 minutes.Remove the lid and stir fry until the eggplant is golden brown. It should be tender but still holding its shape. Remove the eggplant from the pan and set aside. 2 tbsp neutral oil, 2 Japanese eggplants
Stir Fry Peppers & Onions: Heat the remaining 1 tbsp oil over medium-high. Add onions and peppers. Cook for 5-6 min, stirring often, until tender-crisp.

Add Aromatics: Add garlic, ginger and Thai chili. Cook for 1 min, stirring constantly, until fragrant.

Add Sauce: To the pan, add the sauce and cornstarch slurry, making sure to re-mix the slurry as the cornstarch will have settled to the bottom.
Add Eggplant and Thai Basil: Bring to a simmer. Once simmering, reduce heat to medium. Add eggplant to the pan. Cook for another 2 minutes stirring often, until slightly reduced, saucy and eggplant absorbs some of the sauce. Turn off the heat and stir in the Thai basil.
