Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Dice the zucchini, red bell pepper, and red onion into bite-sized pieces.
Toss the vegetables with 0.5 tsp of olive oil, dried oregano, and half of the salt and pepper.
Spread the vegetables on the baking sheet and roast for 15-18 minutes until tender and slightly charred.
While vegetables roast, season the chicken breast with the remaining salt and pepper.
Heat the remaining 0.5 tsp of olive oil in a non-stick skillet over medium-high heat.
Cook the chicken for 5-7 minutes per side until the internal temperature reaches 165°F, then slice into strips.
Spread the hummus in a thick layer on the bottom of a shallow bowl or plate.
Arrange the roasted vegetables and sliced chicken on top of the hummus.
Finish the platter by sprinkling with crumbled feta cheese and drizzling with fresh lemon juice.
