Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Slice the chicken breast into thin strips and place them in a mixing bowl.
Chop the zucchini and red bell pepper into bite-sized pieces and add them to the bowl with the chicken.
Drizzle the olive oil over the chicken and vegetables, then sprinkle with dried oregano, sea salt, and black pepper.
Toss everything together until evenly coated, then spread the mixture in a single layer on the prepared baking sheet.
Roast in the oven for 18 to 20 minutes, or until the chicken is cooked through and the vegetables are tender and slightly charred.
While the chicken and vegetables roast, slice the fresh cucumber into thin rounds and finely chop the parsley.
To assemble, spread the hummus in a circular motion on a large plate or shallow bowl to create a base.
Arrange the warm roasted chicken, charred vegetables, and cool cucumber rounds on top of the hummus.
Finish the platter with a fresh squeeze of lemon juice and a garnish of chopped parsley before serving.
