Cut the chicken breast into bite-sized cubes and season evenly with dried oregano, garlic powder, sea salt, and black pepper.
Slice the zucchini into half-moons, chop the red bell pepper into squares, and cut the red onion into thin wedges.
Heat the olive oil in a large skillet over medium-high heat.
Add the seasoned chicken to the skillet and sauté for 5-6 minutes until golden brown and cooked through.
Add the zucchini, bell peppers, and red onion to the skillet with the chicken and cook for another 4-5 minutes until the vegetables are tender-crisp and slightly charred.
Spread the hummus in a smooth layer across the bottom of a shallow bowl or plate.
Top the hummus with the warm chicken and vegetable mixture.
Garnish the platter with crumbled feta cheese, chopped fresh parsley, and a bright squeeze of lemon juice before serving.
