Place the sweet potatoes and chickpeas on the prepared baking sheet. Add the olive oil, smoked paprika, cumin, garlic powder, oregano, salt, and black pepper.
Toss until evenly coated. Spread the mixture into an even layer. Roast for 15 minutes.
Stir the sweet potatoes and chickpeas. Roast for another 10 to 15 minutes, or until the sweet potatoes are tender and browned and the chickpeas are lightly crisp.
Add the quinoa and vegetable broth to a medium saucepan.
Bring the broth to a boil over medium-high heat. Reduce the heat to low. Cover the saucepan. Simmer for about 15 minutes, or until the quinoa has absorbed the broth.
Remove the saucepan from the heat. Let the quinoa stand, covered, for 5 minutes. Fluff the quinoa with a fork.
In a small bowl, add the Greek yogurt, tahini, lemon juice, water, garlic, oregano, salt, and black pepper. Using a wire whisk, mix until smooth.
Divide the quinoa, romaine, tomatoes, cucumber, red bell pepper, and red onion among 4 bowls. Add the roasted sweet potatoes and chickpeas.
Top each bowl with feta cheese and parsley. Drizzle the lemon tahini yogurt sauce over each bowl.
Notes
Tips and Tricks
Keep the ingredients separate for meal prep - Store the lettuce and chopped vegetables away from the warm ingredients and sauce so they stay crisp.Thin the sauce as needed - Tahini can make the sauce thicken as it sits. Stir in water, 1 teaspoon at a time, until it reaches the consistency you want.Use a wide baking sheet - Give the sweet potatoes and chickpeas room to roast. An overcrowded pan can make them steam.
