01 - Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
02 - Using a vegetable peeler, slice the peeled carrots lengthwise into thin, even ribbons.
03 - Toss carrot ribbons with 1 tablespoon olive oil, salt, and pepper. Spread in a single layer on the prepared baking sheet. Roast for 15-18 minutes, flipping halfway through, until tender and lightly caramelized.
04 - Combine rinsed quinoa and water or vegetable broth in a saucepan. Bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes until all liquid is absorbed. Fluff with a fork and keep warm.
05 - In a small bowl, whisk together tahini, remaining olive oil, lemon juice, maple syrup or honey, minced garlic, and 2-3 tablespoons of water until smooth and creamy. Season with salt and pepper. Adjust consistency with additional water as needed.
06 - In a large bowl, combine the warm quinoa, roasted carrot ribbons, baby spinach, sliced red onion, and chopped parsley. Drizzle with the lemon-tahini dressing and toss gently until evenly coated.
07 - Sprinkle with toasted pumpkin seeds and crumbled feta cheese if desired. Serve warm or at room temperature.
