Step 1: Roast the Cauliflower and Chickpeas : Preheat oven to 425°F (220°C) and line a baking sheet with parchment paper. In a large bowl, toss cauliflower florets and chickpeas with olive oil, cumin, paprika, salt, and pepper. Spread evenly on the baking sheet in a single layer. Roast for 25 minutes, flipping halfway through, until cauliflower is golden brown and slightly crisp on the edges.
Step 2: Prepare the Lemon Tahini Dressing : In a small bowl, whisk together tahini, lemon juice, olive oil, garlic, and a pinch of salt. Slowly add warm water, 1 tablespoon at a time, until you reach a smooth, pourable consistency.
Step 3: Assemble the Salad : In a large salad bowl, combine roasted cauliflower and chickpeas with sliced red onion, parsley, and mint. Drizzle the lemon-tahini dressing over the top and toss gently to coat. Taste and adjust salt or lemon juice if needed.
Step 4: Garnish and Serve : Sprinkle with toasted nuts or seeds before serving for extra crunch and flavor.
