01 - Set oven to 425°F and allow to fully preheat before proceeding.
02 - Toss sliced rainbow carrots with olive oil, sea salt, and black pepper. Arrange in a single layer on a baking sheet. Roast for 25 to 30 minutes, stirring once halfway, until carrots are golden and tender.
03 - Rinse quinoa under cold running water. Combine quinoa, water, and salt in a medium saucepan. Bring to a boil over medium-high heat, reduce to low, cover, and simmer for 15 minutes. Remove from heat and rest, covered, for 5 minutes. Fluff quinoa gently with a fork.
04 - In a mixing bowl, whisk together tahini, freshly squeezed lemon juice, honey, warm water, minced garlic, and salt until smooth. Incorporate additional water as needed to reach a creamy, pourable consistency.
05 - Divide cooked quinoa among four serving bowls. Top with mixed greens, roasted carrots, avocado slices, pepitas, crumbled feta cheese if desired, and a sprinkle of chopped parsley.
06 - Drizzle bowls generously with honey lemon tahini dressing and serve immediately.
