Preheat the oven to 220 °C fan.
Press the tofu well, then tear into chunky pieces. Toss with the oil and cornstarch until lightly coated. Spread out on a lined baking tray.
Bake for 25 to 30 minutes, turning halfway, until deeply golden and crisp around the edges.
Mix the garlic, gochujang, chili flakes, dark soy, rice vinegar, sugar and sesame oil into a thick sauce.
Remove the tofu from the oven, toss with the sauce, then return to the oven for 5 to 7 minutes until sticky and glossy.
Whisk the tahini, miso, rice vinegar and soy sauce. Add water gradually until smooth and pourable.
Combine all salad ingredients. Let sit for 5 minutes so it lightly pickles and softens.
Cook the noodles according to the package. Drain and mix while hot with the tahini miso sauce.
Divide noodles between bowls. Top with spicy oven baked tofu and plenty of herb salad. Finish with sesame seeds and chili crisp.
