Bring medium saucepan of salted water to a boil. Add noodles to boiling water and cook until noodles are tender, 5 to 6 minutes. Drain and rinse noodles with cold water to stop cooking process.

Combine vinegar, tamari, sugar, chili garlic sauce, and 3 tbsp water in medium bowl. Set aside. Heat 1 tbsp vegetable oil in same saucepan over medium-high heat. Add just 2 garlic cloves and ginger. Cook, stirring occasionally, until fragrant, 2 to 3 minutes. Pour in sauce mixture and cook until starting to thicken, 2 to 3 minutes. Add in tofu and noodles, stirring constantly until tofu and noodles are coated, 3 to 5 minutes.

Place oven rack in top third position and set your oven to broil. Combine gai lan, remaining garlic, sesame oil, and a pinch of salt and pepper on foil-lined baking sheet. Broil until bright green and crisp-tender, 3 to 4 minutes. (TIP: All broilers are different, so watch carefully.)

Divide noodles and tofu between bowls and top with garlicky greens. Sprinkle with sesame seeds. Enjoy!
