Cook the farfalle pasta according to the package directions until al dente. Drain well and rinse with cold water to stop the cooking process. Allow the pasta to cool completely.
Heat a lightly oiled grill pan over medium heat.
Slice each chicken breast in half lengthwise to create four thinner pieces.
Season both sides of the chicken with Stone House Seasoning.
Grill for about 4 minutes per side, or until the chicken reaches an internal temperature of 165°F (74°C).
Remove from the pan and let the chicken rest for 5 minutes before cutting into bite-sized pieces.
In a large serving bowl, combine the cooled pasta, grilled chicken, tomatoes, cucumber, green bell pepper, red bell pepper, onion, black olives, and feta cheese.
In a small bowl, whisk together olive oil, red wine vinegar, Stone House Seasoning, oregano, basil, and Dijon mustard until smooth.
Pour the dressing over the salad and gently toss until everything is evenly coated.
Refrigerate the Greek Chicken Pasta Salad for at least 20 minutes before serving for the best flavor.
