01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - In a large bowl, toss cauliflower florets with olive oil, kosher salt, and black pepper until evenly coated.
03 - Spread cauliflower in a single layer on the prepared baking sheet. Roast for 30 to 35 minutes, flipping halfway through, until golden and tender with crispy edges.
04 - While the cauliflower roasts, whisk together tahini, lemon juice, minced garlic, maple syrup (if using), salt, and 2 tablespoons water in a small bowl. Add extra water, 1 teaspoon at a time, until a drizzling consistency is reached.
05 - In a separate bowl, combine chopped almonds, pumpkin seeds, parsley, lemon zest, olive oil, and a pinch of sea salt. Toss until evenly mixed.
06 - Arrange roasted cauliflower on a serving platter. Drizzle generously with lemon tahini sauce, then sprinkle with the nut and herb crunch. Serve warm or at room temperature.
