01 - Preheat the oven to 400°F (200°C).
02 - In a medium saucepan, bring barley, water, and salt to a boil. Reduce heat, cover, and simmer for 25–30 minutes until barley is tender and water is absorbed. Fluff with a fork and set aside.
03 - While the barley cooks, toss sweet potato, bell pepper, and red onion with olive oil, cumin, paprika, coriander, cinnamon, chili flakes, salt, and pepper. Spread on a baking sheet and roast for 25 minutes, tossing halfway, until vegetables are golden and tender.
04 - In a large skillet over medium heat, wilt the spinach for 1–2 minutes until just softened.
05 - Divide cooked barley among 4 bowls. Top with roasted vegetables and wilted spinach.
06 - Sprinkle with toasted pumpkin seeds and chopped herbs. Serve with lemon wedges.
