Season the chicken breast evenly with the sea salt, black pepper, and garlic powder.
Heat the extra virgin olive oil in a skillet over medium-high heat.
Add the chicken breast to the skillet and cook for 6-7 minutes per side until golden brown and the internal temperature reaches 165°F.
While the chicken is cooking, dice the cucumber into half-moons and finely mince the red onion.
Rinse and drain the butter beans thoroughly.
In a large mixing bowl, combine the butter beans, diced cucumber, and minced red onion.
Once the chicken is finished, remove it from the heat and let it rest for 5 minutes before slicing into bite-sized cubes.
Add the sliced chicken to the bowl with the vegetables and beans.
Drizzle the balsamic vinegar over the salad and toss gently to coat all ingredients.
Garnish with freshly chopped parsley and serve immediately.
