01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - In a medium saucepan, combine quinoa, water, and salt. Bring to a boil, reduce heat to low, cover, and simmer for 15 minutes. Remove from heat and let stand, covered, for 5 minutes. Fluff with a fork.
03 - While quinoa cooks, toss artichoke quarters with olive oil, smoked paprika, garlic powder, salt, and black pepper. Arrange in a single layer on the prepared baking sheet.
04 - Roast artichokes for 25-30 minutes, turning halfway, until golden brown and crisp at the edges.
05 - In a bowl, whisk together tahini, lemon juice, olive oil, maple syrup, garlic, salt, and black pepper. Whisk in water, 1 tablespoon at a time, until the dressing is smooth and pourable.
06 - Divide quinoa among four bowls. Top each with baby spinach, tomatoes, cucumber, red onion, parsley, and crispy artichokes. Drizzle generously with lemon tahini dressing.
07 - Serve immediately, or chill for a refreshing cold grain bowl.
