Preheat your oven to 425°F (220°C). On a large rimmed baking sheet, combine the cauliflower florets and sliced carrots.
Drizzle the vegetables with 2 tablespoons of olive oil, smoked paprika, garlic powder, cumin, salt, and pepper. Toss well to coat everything evenly.
Roast for 25 to 30 minutes, tossing halfway through, until the vegetables are tender and browned in spots.
While the vegetables roast, combine the rinsed quinoa and vegetable broth in a medium saucepan. Bring to a boil over medium-high heat, then reduce the heat to low, cover, and simmer for 15 minutes, or until all the liquid is absorbed.
In a small bowl, prepare the dressing. Whisk together the tahini, sherry vinegar, maple syrup, chili garlic sauce, curry powder, turmeric, and salt. Gradually add water, 1 tablespoon at a time, whisking until the dressing is smooth and pourable.
Once the quinoa is cooked, remove it from the heat. Add the chopped kale and the remaining 1 tablespoon of olive oil. Stir to combine, then cover the pot and let it stand for 5 minutes to allow the kale to wilt.
To assemble, divide the quinoa and kale mixture among four bowls. Top with the roasted vegetables, sliced avocado, and a sprinkle of pumpkin seeds. Drizzle with the tahini dressing and garnish with fresh parsley, if using.
