Season the chicken breast with half of the garlic powder, sea salt, and black pepper.
Grill the chicken over medium-high heat for 6-7 minutes per side until the internal temperature reaches 165 degrees Fahrenheit, then slice into thin strips.
In a small food processor, blend the chickpeas, tahini, lemon juice, and the remaining garlic powder until the mixture is velvety and smooth.
Slice the whole wheat pita into triangles and toast in a dry skillet over medium heat until golden and crispy on both sides.
Finely dice the cucumber and cherry tomatoes, then toss them in a small bowl with the olive oil, fresh parsley, and the remaining sea salt and black pepper.
Spread the hummus in a shallow bowl, top with the grilled chicken strips, and serve with the pita chips and cucumber-tomato salad on the side.
