Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Rinse and thoroughly pat the chickpeas dry with a clean kitchen towel to ensure they get maximum crispiness during roasting.
In a large bowl, toss the chickpeas and cauliflower florets with olive oil, sea salt, smoked paprika, and garlic powder until evenly coated.
Spread the mixture in a single layer on the baking sheet and roast for 25 to 30 minutes, shaking the pan halfway through, until the vegetables are tender and the chickpeas are golden.
While the vegetables roast, whisk together the Greek yogurt, lemon juice, and nutritional yeast in a small bowl until smooth and creamy.
To assemble, spread the savory yogurt mixture at the bottom of a bowl and top with the warm roasted vegetables and chickpeas.
Garnish with hemp hearts and fresh parsley for an added boost of plant-based protein and a bright finish.
