Preheat your oven to 400°F (200°C).
Place the chicken breast on a parchment-lined baking sheet and rub with olive oil, dried oregano, garlic powder, sea salt, and black pepper.
Roast the chicken for 18-20 minutes or until the internal temperature reaches 165°F.
Remove the chicken from the oven and let it rest for 5 minutes before slicing into strips.
While the chicken rests, slice the cucumber into rounds and halve the cherry tomatoes.
Thinly slice the red onion and finely chop the fresh parsley.
Arrange the sliced chicken, hummus, cucumbers, tomatoes, olives, and red onion on a large serving plate.
Drizzle the lemon juice over the vegetables and garnish the entire platter with fresh parsley.
