To a medium bowl, add all ingredients, whisk to combine; set aside. Note – You are only adding the juice from one can of mandarins to the vinaigrette. Add the mandarins to a separate very large bowl.
Cook pasta according to package directions, drain, and add it to the bowl with the mandarins.
While the pasta is cooking, to a large skillet add the sesame oil, olive oil, chicken, season with salt and pepper, and cook over medium-high heat for about 5 minutes, or until chicken is cooked through; stir and flip intermittently to ensure even cooking.
Add chicken and all cooking juices to the bowl with the mandarins and pasta.
Add the peppers, carrots, cucumbers, additional one can of mandarins (drain juice and discard), spinach, add the vinaigrette, stir and toss to combine and coat evenly.
Taste the salad and make any additional flavor adjustments such as more salt, pepper, sugar, vinegar, cayenne (doesn’t make it hot but adds flavor), etc. and either serve immediately or chill before serving.
