Preheat your oven to 400°F (200°C).
Slice the chicken breast, red bell pepper, and zucchini into uniform, bite-sized pieces.
Place the chicken and vegetables on a large parchment-lined baking sheet.
Drizzle with olive oil and season evenly with dried oregano, sea salt, and black pepper.
Toss well to coat and spread the ingredients in a single layer to ensure even roasting.
Roast for 18 to 20 minutes, or until the chicken is cooked through and the vegetables are tender and slightly charred.
Spread the hummus in a thick, smooth layer across the bottom of a large plate or shallow bowl.
Arrange the roasted chicken and vegetables over the hummus.
Finish with a bright squeeze of fresh lemon juice and a garnish of chopped fresh parsley.
