Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Dice the chicken breast into 1-inch cubes and chop the red bell pepper, zucchini, and red onion into bite-sized pieces.
Place the chicken and vegetables on the baking sheet, drizzle with olive oil, and season with dried oregano, sea salt, and black pepper.
Toss everything together until evenly coated, then spread into a single layer.
Roast in the oven for 18-20 minutes, or until the chicken is cooked through and the vegetables are tender and slightly charred.
Spread the hummus in a wide circle on a serving plate or bowl.
Pile the roasted chicken and vegetables directly onto the hummus base.
Garnish the platter with crumbled feta cheese, a squeeze of fresh lemon juice, and chopped fresh parsley before serving.
