01 - Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.
02 - Toss sweet potato, broccoli, and cauliflower with olive oil, smoked paprika, salt, and pepper. Spread in an even layer on the prepared baking sheet. Roast for 20–25 minutes, stirring halfway through, until tender and lightly caramelized at the edges.
03 - While the vegetables roast, combine rinsed quinoa, water, and a pinch of salt in a saucepan. Bring to a boil over medium-high heat, then reduce to low, cover, and simmer for 15 minutes until all liquid is absorbed. Remove from heat and let rest, covered, for 5 minutes. Fluff with a fork.
04 - In a small bowl, whisk together tahini, lemon juice, maple syrup, water, minced garlic, salt, and pepper until smooth and creamy. Add additional water 1 teaspoon at a time if a thinner consistency is desired.
05 - Divide the fluffy quinoa among 4 bowls. Arrange roasted vegetables, cherry tomatoes, red cabbage, avocado slices, and baby spinach over each portion. Drizzle generously with tahini dressing and sprinkle with pumpkin seeds.
06 - Serve immediately while the roasted vegetables are still warm. Enjoy!
