Heat a stainless steel wok or skillet over high heat. Add neutral oil and the white parts of the scallions. Stir for 15 seconds, then add the tomatoes.
Stir-fry for 2 minutes, then add Shaoxing wine around the pan’s edge.
Add water (or stock), sugar, salt, vegetarian oyster sauce, light soy sauce, sesame oil, and white pepper. Simmer for 1 minute until tomatoes soften.
Prepare a cornstarch slurry and stir it into the sauce to thicken. Add tofu, gently mixing to avoid breaking it.
Reduce heat to medium, cover, and cook for 2 minutes until the tomatoes and sauce are thickened. Adjust with more slurry if needed.
Uncover, stir in scallions, and season with salt and sugar to taste. Serve with jasmine rice and enjoy!
