Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Slice the chicken breast into thin, even strips and chop the bell pepper, zucchini, and red onion into bite-sized pieces.
Place the chicken and vegetables on the prepared baking sheet.
Drizzle with olive oil and sprinkle with sea salt, black pepper, and dried oregano, tossing well to coat everything evenly.
Spread the mixture in a single layer and roast for 18 to 20 minutes, or until the chicken is cooked through and the vegetables are tender.
While the chicken roasts, spread the hummus in a wide circle onto a large plate or shallow bowl.
Arrange the roasted chicken and vegetables directly on top of the hummus.
Finish with a fresh squeeze of lemon juice over the entire platter before serving.
