Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Slice the chicken breast into bite-sized strips and place them on the baking sheet along with the sliced bell peppers and zucchini.
Drizzle the olive oil over the chicken and vegetables, then sprinkle with sea salt, black pepper, and dried oregano, tossing to coat evenly.
Roast in the oven for 18 to 22 minutes, or until the chicken is fully cooked and the vegetables are tender and slightly caramelized.
While the chicken roasts, slice the fresh cucumber and halve the cherry tomatoes.
Spread the hummus in a thick layer across the base of a large plate or shallow bowl.
Arrange the warm roasted chicken and vegetables over the hummus, then top with the fresh cucumber and tomatoes.
Squeeze the fresh lemon juice over the entire platter before serving.
