01 - Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
02 - Toss the cubed sweet potato, broccoli florets, and cauliflower florets with olive oil, smoked paprika, salt, and pepper until evenly coated. Spread in a single layer on the prepared baking sheet. Roast for 20–25 minutes, stirring halfway through, until the vegetables are tender and lightly caramelized at the edges.
03 - While the vegetables roast, combine the rinsed quinoa, water, and a pinch of salt in a medium saucepan. Bring to a rolling boil over medium-high heat, then reduce the heat to low, cover, and simmer for 15 minutes or until all liquid is absorbed. Remove from heat and let rest, covered, for 5 minutes. Fluff gently with a fork before serving.
04 - In a small mixing bowl, whisk together the tahini, lemon juice, maple syrup, minced garlic, water, salt, and pepper until completely smooth. Add additional water, one teaspoon at a time, until the dressing reaches your desired drizzling consistency.
05 - Divide the fluffed quinoa evenly among four bowls. Arrange the roasted sweet potato, broccoli, and cauliflower alongside the halved cherry tomatoes, sliced red cabbage, baby spinach, and sliced avocado. Drizzle generously with the tahini dressing and finish with a sprinkle of pumpkin seeds.
06 - Serve immediately while the roasted vegetables are still warm. Enjoy!
