Preheat your oven to 400°F (200°C).
Slice the zucchini and red bell pepper into bite-sized pieces.
On a parchment-lined baking sheet, toss the zucchini, bell pepper, and cherry tomatoes with 1 teaspoon of olive oil, dried oregano, and a pinch of salt and pepper.
Roast the vegetables for 15-20 minutes until they are tender and slightly caramelized.
While the vegetables roast, season the chicken breast with salt and pepper, then grill or pan-sear over medium-high heat for 5-7 minutes per side until fully cooked.
In a small food processor or blender, combine the chickpeas, tahini, Greek yogurt, lemon juice, garlic, and the remaining 1 teaspoon of olive oil. Blend until completely smooth.
Spread the high-protein hummus onto a large plate or shallow bowl.
Top the hummus with the warm roasted vegetables and the sliced grilled chicken.
Garnish the platter with freshly chopped parsley and an extra crack of black pepper before serving.
