Preheat your oven to 400°F (200°C).
Slice the zucchini into rounds, the red bell pepper into strips, and the red onion into small wedges.
Toss the vegetables on a baking sheet with half of the olive oil, half of the sea salt, and half of the dried oregano.
Roast the vegetables for 15-20 minutes until tender and slightly charred at the edges.
While vegetables roast, season the chicken breast with the remaining sea salt, black pepper, and dried oregano.
Heat the remaining olive oil in a skillet over medium-high heat and sear the chicken for 6-7 minutes per side until the internal temperature reaches 165°F.
Remove the chicken from the heat, let it rest for 3 minutes, then slice into thin strips.
Spread the hummus in a thick layer across a serving plate.
Arrange the roasted vegetables and sliced chicken over the hummus, then drizzle with fresh lemon juice before serving.
