Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Slice the chicken breast into bite-sized strips and chop the bell pepper, zucchini, and red onion into uniform pieces.
Place the chicken and vegetables on the baking sheet, drizzle with olive oil, and season with sea salt, black pepper, and dried oregano.
Toss everything together until evenly coated and roast for 18-20 minutes, or until the chicken is cooked through and vegetables are slightly charred.
While roasting, whisk the hummus and Greek yogurt together in a small bowl until smooth and fluffy.
Spread the hummus mixture across the bottom of a shallow bowl or platter using the back of a spoon.
Arrange the roasted chicken and vegetables over the hummus base.
Garnish the platter with crumbled feta cheese and a fresh squeeze of lemon juice before serving.
