01 - Set oven to 425°F (220°C) and line a baking sheet with parchment paper.
02 - In a large bowl, toss the cauliflower florets with olive oil, cumin, smoked paprika, sea salt, and black pepper until evenly coated.
03 - Arrange the florets in a single layer on the prepared baking sheet. Roast for 25 to 30 minutes, flipping halfway through, until golden brown and tender.
04 - While the cauliflower roasts, combine tahini, parsley, cilantro, lemon juice, garlic, water, and sea salt in a blender or food processor. Blend until smooth and bright green, adjusting consistency with additional water as needed. Taste and season as preferred.
05 - Transfer the roasted cauliflower to a serving platter and drizzle generously with the green tahini sauce.
06 - Sprinkle with toasted pine nuts, extra chopped herbs, and serve with lemon wedges if desired. Serve warm or at room temperature.
