Season the chicken breast with a pinch of sea salt and black pepper.
Heat a non-stick skillet over medium-high heat and sauté the chicken for 5-7 minutes per side until cooked through and golden brown.
While the chicken cooks, steam the fresh green beans for 3 minutes until tender-crisp, then immediately plunge them into ice water to stop the cooking and preserve the color.
Rinse and drain the canned chickpeas and kidney beans thoroughly to remove excess sodium.
Finely dice the red bell pepper and red onion, and chop the fresh parsley.
In a small bowl, whisk together the extra virgin olive oil, lemon juice, Dijon mustard, dried oregano, and the remaining sea salt and pepper to create the vinaigrette.
In a large mixing bowl, combine the chickpeas, kidney beans, steamed green beans, bell pepper, and onion.
Slice the cooked chicken breast into bite-sized strips.
Pour the vinaigrette over the bean mixture and toss well to coat.
Top the salad with the sliced chicken and fresh parsley before serving.
