01 - Rinse barley under cold running water. Combine with 2½ cups water and ½ teaspoon salt in a medium saucepan. Bring to a rolling boil, then reduce heat to low, cover, and simmer for 25–30 minutes until grains are tender and most liquid is absorbed. Drain any remaining liquid and set aside.
02 - Heat olive oil in a large skillet over medium heat. Add diced zucchini and cook for 3–4 minutes, stirring occasionally, until lightly golden and slightly softened.
03 - Stir in minced garlic and sliced green onions. Sauté for 1 minute until fragrant, taking care not to brown the garlic.
04 - Add chopped spinach to the skillet and toss gently until just wilted, about 1–2 minutes. Season with a pinch of salt and freshly ground black pepper. Remove from heat.
05 - In a separate nonstick skillet, cook eggs to your preference — sunny-side up, over-easy, poached, or soft-boiled — until whites are set and yolks are still runny.
06 - Divide cooked barley evenly between two serving bowls. Layer the sautéed vegetable mixture over the barley and top each bowl with a cooked egg.
07 - Finish each bowl with crumbled feta cheese, chopped fresh parsley, and an extra crack of black pepper. Serve immediately while warm.
