Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Cut the chicken breast, red bell pepper, and zucchini into uniform 1-inch pieces to ensure they cook evenly.
Place the chicken and chopped vegetables on the baking sheet, drizzle with olive oil, and season with sea salt, black pepper, and dried oregano.
Toss the mixture thoroughly to coat every piece, then spread it out in a single layer and roast for 18-20 minutes until the chicken is fully cooked.
While the chicken and vegetables are roasting, slice the cherry tomatoes in half and set them aside.
Spread the hummus in a thick, even layer across the bottom of a large plate or shallow bowl to create a smooth base.
Top the hummus with the warm roasted chicken and vegetables, then scatter the fresh cherry tomatoes and crumbled feta cheese over the top.
Finish the platter with a squeeze of fresh lemon juice to add a bright, acidic pop that balances the savory flavors.
