Season the chicken breast evenly with garlic powder, half of the sea salt, and half of the black pepper.
Heat the olive oil in a skillet over medium heat and cook the chicken for 5-7 minutes per side until the internal temperature reaches 165°F.
While the chicken cooks, place the chickpeas, tahini, roasted red peppers, lemon juice, and the remaining salt and pepper into a food processor.
Blend the hummus mixture until it is completely smooth and creamy, adding a tablespoon of water if needed to adjust the texture.
Spread the prepared roasted red pepper hummus in a thick, circular layer onto a large serving plate.
Slice the cooked chicken breast into thin strips and arrange them in the center of the hummus bed.
Surround the chicken with sliced cucumbers, halved cherry tomatoes, and kalamata olives.
Garnish the entire platter with finely chopped fresh parsley and serve immediately.
