Season the chicken breast with salt and poach for 12–15 minutes, or until the internal temperature reaches 165°F. Let cool, then shred.
Cook the noodles according to the package instructions. Drain and rinse under cold water.
Make the sesame sauce by whisking together 3 tablespoons Chinese sesame paste, soy sauce, rice vinegar, honey, sesame oil, garlic, and chili oil.
Gradually whisk in 3–5 tablespoons warm water until the sauce reaches a smooth, pourable consistency.
Toss the cold noodles with the shredded chicken and sesame sauce.
Top with cucumber, green onions, sesame seeds, and any additional chili oil or chili crisp.
Enjoy.
