Bring a large pot of salted water to a boil. Add the whole wheat pasta and cook according to package instructions until al dente.

Once cooked, drain the pasta in a colander and rinse under cold water to cool.

In a mixing bowl, whisk together the olive oil, red wine vinegar, honey, garlic powder, dried oregano, salt, and black pepper until well combined.

In a large mixing bowl, combine the cooled pasta, cooked chicken, cherry tomatoes, cucumber, and bell pepper.

Pour the dressing over the pasta salad and toss until everything is evenly coated.

Chill in the refrigerator for at least 10 minutes before serving. Serve cold or at room temperature.
