Season the chicken breast evenly with the dried oregano, sea salt, and black pepper.
Heat the extra virgin olive oil in a medium skillet over medium-high heat.
Sear the chicken for 6-7 minutes per side until golden brown and the internal temperature reaches 165 degrees Fahrenheit.
While the chicken cooks, combine chickpeas, tahini, lemon juice, and garlic in a food processor and blend until smooth.
Slice the cooked chicken into thin strips and dice the cucumber and cherry tomatoes.
Spread the fresh hummus across the base of a large plate or shallow bowl.
Top the hummus with the sliced chicken, cucumber, tomatoes, and kalamata olives.
Finish the platter by sprinkling with crumbled feta cheese and finely chopped fresh parsley.
