Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Slice the red bell pepper, zucchini, and red onion into bite-sized pieces.
In a mixing bowl, toss the vegetables with the olive oil, dried oregano, sea salt, and black pepper until evenly coated.
Spread the vegetables in a single layer on the prepared baking sheet and roast for 18-20 minutes until tender and slightly charred.
While the vegetables roast, season the chicken breast with a small pinch of salt and pepper and sear in a non-stick skillet over medium-high heat for 6-7 minutes per side until the internal temperature reaches 165°F.
Remove the chicken from the pan and let it rest for 3 minutes before slicing it into thin strips.
Spread the hummus in a wide, smooth circle on a large serving plate or shallow bowl.
Arrange the warm roasted vegetables and sliced chicken strips directly on top of the hummus base.
Finish the platter by crumbling the feta cheese over the top and drizzling with fresh lemon juice before serving.
