Preheat your oven to 400F and line a large rimmed baking sheet with parchment paper.
Pat the cooked chickpeas thoroughly dry with a paper towel to ensure they achieve a satisfying crunch when roasted.
In a large bowl, toss the chickpeas, broccoli florets, and bell pepper strips with olive oil, smoked paprika, garlic powder, sea salt, and black pepper.
Spread the vegetable and chickpea mixture in a single layer on the prepared baking sheet.
Roast for 20 to 25 minutes, tossing halfway through, until the vegetables are tender and the chickpeas are lightly browned.
While the medley roasts, whisk together the Greek yogurt, nutritional yeast, lemon juice, and dried oregano in a small bowl until smooth.
Spread the high-protein yogurt mixture onto the base of a shallow bowl or plate.
Top the yogurt with the warm roasted chickpea and vegetable medley and serve immediately.
