Separate the white and green parts of the scallions then cut the white into bite-size chunks. For the green parts, I sliced them into tiny ‘coins’ for garnish. Same goes with the chili.
Heat a large wok over medium heat and add 2 heaping tablespoons oil (you may use less for non-stick pan). Slowly slide in the tofu. Use a spatula or spoon and cut up tofu into chunks. Let each side pan fry until slightly golden where tofu can hold their shape. Tip - only flip the tofu once a crust is formed.
Meanwhile, in the bowl with white scallions part, stir together vegan oyster sauce, soy sauce, sugar, and cornstarch with water until well combined.
When tofu is done, add the sauce, and gently toss to combine. Let it simmer for about 30 seconds until flavors meld, with a few toss in between to prevent tofu from sticking. Taste test and adjust saltiness with more soy sauce if needed or additional water for a saucier dish.
Garnish with green parts of scallions and chili and give it a final toss.
Serve immediately with a bowl of rice.
