Season the chicken breast evenly with half of the sea salt, black pepper, and garlic powder.
Grill the chicken over medium-high heat for approximately 6-7 minutes per side until the internal temperature reaches 165°F.
While the chicken is cooking, combine the rinsed chickpeas, roasted red peppers, tahini, lemon juice, olive oil, and the remaining seasonings in a food processor.
Blend the hummus mixture until it reaches a velvety, smooth consistency, adding a teaspoon of water if needed to reach your desired thickness.
Remove the chicken from the grill and allow it to rest for 3 minutes before slicing it into thin strips.
Spread the roasted red pepper hummus across the base of a large plate or shallow bowl.
Arrange the sliced chicken, sliced cucumbers, and halved cherry tomatoes on top of the hummus bed.
Garnish the platter with freshly chopped parsley and serve immediately.
