Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper for easy cleanup.
Slice the chicken breast into thin, even strips and chop the red bell pepper, zucchini, and red onion into bite-sized pieces.
In a large mixing bowl, combine the chicken strips and chopped vegetables with the extra virgin olive oil, dried oregano, garlic powder, sea salt, and black pepper.
Toss everything thoroughly until the chicken and vegetables are evenly coated in the oil and spices.
Spread the mixture in a single layer on the prepared baking sheet, ensuring space between pieces for even roasting.
Roast in the oven for 18 to 20 minutes, or until the chicken is cooked through and the vegetables are tender and slightly caramelized.
While the chicken roasts, spread the hummus in a thick, circular layer onto the center of a large plate or shallow bowl.
Remove the tray from the oven and pile the roasted chicken and vegetables directly on top of the hummus base.
Finish the dish by drizzling the fresh lemon juice over the top to brighten the flavors before serving immediately.
