Preheat your oven to 400°F (200°C).
Chop the zucchini, red bell pepper, and red onion into uniform bite-sized pieces.
In a bowl, toss the vegetables with half of the olive oil, dried oregano, and a pinch of salt and pepper.
Spread the vegetables onto a parchment-lined baking sheet and roast for 15-20 minutes until tender and slightly charred.
While the vegetables roast, season the chicken breast with garlic powder and the remaining salt and pepper.
Heat the remaining olive oil in a skillet over medium-high heat and sear the chicken for 5-7 minutes per side until the internal temperature reaches 165°F.
Remove the chicken from the heat and slice it into thin strips.
Spread the hummus in a thick layer across the bottom of a large plate or shallow bowl.
Arrange the roasted vegetables and sliced chicken on top of the hummus bed.
Garnish with freshly chopped parsley and enjoy immediately.
