Bring a pot of salted water to a boil and cook the chickpea pasta according to package directions until al dente, then drain and rinse with cold water to stop the cooking process.
Season the chicken breast with sea salt and black pepper, then grill or pan-sear over medium-high heat until cooked through and the internal temperature reaches 165°F.
Allow the chicken to rest for five minutes before slicing into bite-sized strips or cubes.
Halve the cherry tomatoes, dice the cucumber and red bell pepper, and finely mince the red onion.
In a small mixing bowl, whisk together the extra virgin olive oil, lemon juice, dried oregano, and a pinch of salt and pepper to create the dressing.
In a large salad bowl, combine the cooled chickpea pasta, grilled chicken, cherry tomatoes, cucumber, bell pepper, and red onion.
Pour the lemon-herb dressing over the salad and toss thoroughly to ensure all ingredients are evenly coated.
Crumble the feta cheese over the top and give the salad one final gentle toss before serving chilled.
