Preheat your oven to 400°F and line a baking sheet with parchment paper.
Dice the zucchini, red bell pepper, and red onion into uniform 1-inch pieces.
Toss the vegetables on the prepared sheet with 0.5 tsp of the olive oil, dried oregano, and half of the sea salt and black pepper.
Roast for 20 minutes until the vegetables are tender and slightly caramelized.
Season the chicken breast with the remaining salt and pepper, then pan-sear in a skillet with the remaining 0.5 tsp olive oil over medium heat until cooked through.
In a food processor, blend the chickpeas, tahini, lemon juice, and garlic clove until the hummus is completely smooth and creamy.
Spread the hummus onto a plate, top with the sliced chicken and roasted vegetables, and serve warm.
