01 - Rinse barley under cold water. Combine barley, water, and ½ tsp salt in a medium saucepan. Bring to a boil, reduce heat to low, cover, and simmer for 25–30 minutes until tender. Drain excess water and let cool to room temperature.
02 - Dice the English cucumber. Halve the cherry tomatoes. Finely dice the red onion. Roughly chop the baby spinach or mixed greens.
03 - Whisk together lemon zest and juice, orange juice, olive oil, white wine vinegar, chopped dill, chopped parsley, honey or maple syrup, salt, and black pepper in a small bowl until emulsified.
04 - In a large mixing bowl, combine the cooled barley, diced cucumber, halved tomatoes, diced red onion, and chopped greens.
05 - Pour the citrus herb dressing over the barley mixture. Toss gently to coat all ingredients evenly. Taste and adjust seasoning if needed.
06 - Divide into individual serving bowls. Top with toasted pumpkin seeds and crumbled feta cheese if desired.
