Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Toss the sliced bell pepper, zucchini, and red onion with the olive oil, dried oregano, and half of the sea salt and black pepper.
Spread the vegetables in a single layer on the baking sheet and roast for 18 minutes until they are tender and slightly charred.
While the vegetables roast, season the chicken breast with the remaining sea salt and black pepper.
Heat a non-stick skillet over medium-high heat and cook the chicken for 6 to 7 minutes per side until the internal temperature reaches 165°F.
Let the chicken rest for 3 minutes to keep it juicy, then slice it into thin strips.
Spread the hummus in a wide circle on a large plate or shallow bowl to create a base.
Arrange the roasted vegetables and sliced chicken on top of the hummus.
Finish the platter with a sprinkle of crumbled feta cheese, a drizzle of lemon juice, and fresh parsley.
