Season the chicken breast evenly with the sea salt, black pepper, and garlic powder on both sides.
Heat a non-stick skillet over medium-high heat and sear the chicken for 5-6 minutes per side until golden brown and the internal temperature reaches 165°F.
Remove the chicken from the skillet and let it rest for 5 minutes before dicing it into bite-sized cubes.
In a large mixing bowl, combine the rinsed chickpeas, diced cucumber, diced red bell pepper, and finely chopped red onion.
In a small bowl, whisk together the olive oil, lemon juice, and finely chopped fresh parsley to create the dressing.
Add the diced chicken to the bowl with the vegetables and chickpeas, pour the dressing over the top, and toss thoroughly to combine before serving.
