Begin by preparing the orange dressing. In a small bowl, whisk together the Dijon mustard, low sodium soy sauce, rice vinegar, minced ginger, peanut oil, juice from one orange (adjust according to preference), and optional agave for sweetness. Set aside.
In a large mixing bowl, combine the chopped or pulled apart cooked chicken breast, chopped Romaine lettuce, coleslaw, shredded purple cabbage, and sugar snap peas. Gently toss the ingredients together until evenly distributed.
Carefully add the mandarin oranges to the salad mixture. If using canned mandarin oranges, make sure to drain them thoroughly and rinse with water to remove excess syrup.
Pour the prepared orange dressing over the salad mixture. Use a spatula or salad tongs to gently toss everything together, ensuring that the dressing coats all the ingredients evenly.
Once the salad is well coated with the dressing, transfer it to a serving dish or individual salad bowls.
Garnish the mandarin orange salad with chow mein noodles for a crunchy texture, almond slices for extra heartiness and crunch, and cilantro for added flavor.
Serve immediately and enjoy the refreshing and flavorful Mandarin Orange Salad!
