Season the chicken breast with dried oregano, half of the sea salt, and half of the black pepper.
Heat a grill pan or skillet over medium-high heat with half of the olive oil and cook the chicken for 5-6 minutes per side until fully cooked, then slice into strips.
In a food processor, combine the chickpeas, Greek yogurt, tahini, lemon juice, garlic, and the remaining salt and pepper.
Process the mixture until smooth and creamy, adding a teaspoon of water if needed to reach your desired consistency.
Slice the whole wheat pita into triangles and toast in the oven or toaster until lightly browned and crispy.
Chop the cucumber and cherry tomatoes into bite-sized pieces and finely mince the fresh parsley.
Spread the high-protein hummus onto a plate, top with the grilled chicken strips, and serve alongside the fresh vegetables and crispy pita triangles.
Drizzle with the remaining olive oil and garnish with fresh parsley.
