Cook the noodles according to the package directions until just al dente. Drain immediately and rinse thoroughly under cold running water until completely chilled.

Kitchen Technique: Rinsing removes excess starch, preventing the noodles from sticking while creating the perfect chewy texture for cold noodle dishes.

In a large bowl, combine the diced tomatoes, soy sauce, rice vinegar, lemon juice, sesame oil, mushroom powder, and black pepper.

Let the mixture rest for 10–15 minutes so the tomatoes release their juices and naturally create the dressing.

Kitchen Technique: Resting the tomatoes allows osmosis to pull moisture from the fruit, creating a flavorful sauce without additional cooking.

Add the chilled noodles to the bowl and gently toss until every strand is coated in the tomato dressing. Fold in most of the scallions and sesame seeds.

Kitchen Tip: Toss gently with tongs to avoid crushing the tomatoes while evenly coating the noodles.

Taste the noodles and adjust with additional soy sauce for saltiness, lemon juice for brightness, or sesame oil for richness.

Kitchen Tip: The flavor should be balanced—bright, savory, and lightly nutty without one ingredient overpowering the others.

Divide into bowls and top with the remaining scallions, toasted sesame seeds, cracked black pepper, and optional chili crisp for a spicy finish.

Serve immediately or chill for another 15–20 minutes for an even more refreshing meal.
