Heat canola, vegetable, or peanut oil in a pan over medium heat. Fry tofu strips until they turn golden brown. Remove from the pan and set aside. Remove and filter the frying oil to use for future frying projects.
In the same pan, add sesame oil. Sauté thinly sliced shallots, minced garlic, grated ginger, bird’s eye chilies, long green chili, and makrut lime leaves (if using) for 4 minutes over medium heat until they become fragrant.
Add scallions, thinly sliced red pepper, peeled and thinly sliced lengthwise carrots, and Chinese broccoli (if using). Stir-fry until the vegetables become tender but still have a crisp texture.
In a bowl, mix tamari, vegan oyster sauce, palm sugar, rice vinegar, and unsalted vegetable stock (or water). Dissolve cornstarch in this mixture.
Pour the sauce into the pan with the vegetables. Add the fried tofu and the soaked (or fresh) noodles. Toss everything together until well-coated and heated through.
