Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Rinse and drain the chickpeas, then pat them thoroughly dry with a paper towel to ensure they become crunchy when roasted.
On the baking sheet, toss the chickpeas, broccoli florets, and chopped red bell pepper with olive oil, garlic powder, smoked paprika, sea salt, and black pepper until evenly coated.
Spread the mixture in a single layer and roast for 20 minutes, tossing halfway through, until the vegetables are tender and the chickpeas are golden.
While the vegetables roast, whisk together the non-fat Greek yogurt, lemon juice, and nutritional yeast in a small bowl until the sauce is creamy and smooth.
Place the baby spinach in a large serving bowl as the base.
Top the spinach with the warm roasted chickpea and vegetable mixture, drizzle with the zesty yogurt sauce, and finish with a sprinkle of nutty hemp hearts.
