To make the dressing, combine the lime juice, mustard, and olive oil in a jar or container. Seal the container and shake well until all ingredients are fully combined.
In a large bowl, add the chopped romaine lettuce, shredded carrots, diced tomatoes, chopped chicken breast, corn, and sunflower seeds.
Pour the dressing over the salad ingredients and toss everything together until evenly coated.
Slice the oranges into wedges or segments and serve alongside the chicken salad.
