01 - Preheat oven to 400°F. Line two baking sheets with parchment paper for easy cleanup.
02 - Cut the top off the head of garlic to expose cloves, drizzle with a small amount of olive oil, and wrap tightly in foil. Place on one baking sheet.
03 - Toss sweet potato cubes with 1 tablespoon olive oil, salt, and pepper until evenly coated. Spread in a single layer on the same baking sheet as the garlic.
04 - Roast for 25 to 30 minutes, flipping sweet potatoes halfway through cooking, until golden brown and tender when pierced with a fork.
05 - While potatoes roast, toss kale leaves with 1 tablespoon olive oil, salt, and pepper. Massage gently to ensure even coating.
06 - Spread kale on the second baking sheet in a single layer. Bake for 10 to 12 minutes, tossing once halfway through, until edges are crispy but not burnt.
07 - Rinse quinoa thoroughly and combine with 2 cups water and a pinch of salt in a saucepan. Bring to a boil, reduce heat to low, cover, and simmer for 15 minutes. Remove from heat and let stand covered for 5 minutes before fluffing with a fork.
08 - Squeeze roasted garlic cloves from their skins. In a medium bowl, whisk together tahini, lemon juice, maple syrup, cumin, roasted garlic, and a pinch of salt. Gradually add water while whisking until sauce reaches a smooth, pourable consistency.
09 - Divide cooked quinoa among four bowls. Arrange roasted sweet potatoes and crispy kale on top of grains. Add avocado slices, pomegranate seeds, and toasted sesame seeds if desired. Drizzle generously with roasted garlic tahini sauce and garnish with fresh parsley.
