Bring a large pot of water to a boil. Cook noodles according to the package directions. Drain and rinse with cold water to prevent sticking. Set aside.
Heat a wok over medium heat. Add oil and swirl to coat. Add tea leaves (if using), ginger and garlic. Cook, stirring, until fragrant, about 30 seconds. Add tofu and cook, stirring, for 2 minutes. Add red and yellow bell peppers and cook, stirring, until the peppers soften, 1 to 2 minutes.
Stir in the noodles, scallions, soy sauce and rice vinegar. Cook, stirring occasionally, until the noodles are heated through, about 2 minutes. Stir in sesame oil and pepper. Toss to combine. Serve warm or cold.
Precooked "baked tofu" is firmer than water-packed tofu and comes in a wide variety of flavors. We prefer flavors like "teriyaki," "Thai" and "savory" in this recipe. You might also like flavored baked tofu on a sandwich or in a stir-fry.
