Remove chicken from packaging, pat dry, and coat with taco seasoning.
In a large non-stick skillet, heat oil over medium-high heat. Once the oil is shimmering add the chicken and cook for 5-7 on each side or until the internal temperature reaches 165 degrees.
Remove the chicken from the pan, let cool for 10 minutes, then chop into 1/2 inch cubes.
In a large bowl add the enchilada sauce, sour cream and lime juice. Whisk together until smooth.
Add the chicken, pasta, beans, corn, red onion, jalapeno, and olives (optional) to the bowl with the sauce and stir until the pasta is evenly coated.
Top with cilantro, refrigerate for an hour until the pasta is cold. Serve.
