Season the chicken breast with half of the sea salt and black pepper.
Heat a non-stick skillet over medium-high heat and cook the chicken for 6-7 minutes per side until the internal temperature reaches 165°F.
Remove the chicken from the pan, let it rest for 5 minutes, and then dice into bite-sized cubes.
In a small bowl, whisk together the olive oil, lemon juice, minced garlic, ground cumin, and the remaining salt and pepper to create the vinaigrette.
In a large mixing bowl, combine the rinsed garbanzo beans, diced cucumber, halved cherry tomatoes, and finely chopped red onion.
Pour the vinaigrette over the bean and vegetable mixture and toss well to coat.
Add the diced chicken to the salad, garnish with chopped fresh parsley, and serve immediately.
