1. To prepare quinoa, heat 2 teaspoons oil in a large saucepan over medium-high heat. Add 1 garlic clove to pan; sauté 1 minute. Add 1 cup broth and next 4 ingredients (through 1/4 teaspoon salt); cover, reduce heat, and simmer 15 minutes or until liquid is absorbed and quinoa is tender.
2. To prepare chickpea mixture, heat 1 teaspoon oil in a Dutch oven over medium-high heat. Add leek and 4 garlic cloves to pan; sauté 5 minutes or until tender. Add remaining 1 teaspoon oil, fennel bulb, carrot, and fennel seeds; sauté 10 minutes or until vegetables are golden. Add wine; cook 3 minutes or until liquid almost evaporates. Stir in 1 cup broth, 2 teaspoons thyme, and chickpeas; cook 1 minute or until thoroughly heated. Remove from heat; stir in juice, 1/4 teaspoon salt, pepper, and spinach.
3. Place about 2/3 cup quinoa in each of 4 bowls; top each serving with about 1 1/2 cups chickpea mixture. Sprinkle each serving with 1/2 teaspoon thyme.
