A warm grain salad of chewy barley and roasted vegetables that works as a main or a substantial side.
Bring the barley and water to a boil, then simmer 30 minutes until tender. Drain any excess.
Meanwhile, toss the zucchini, pepper, and onion with 1 tbsp oil and roast at 425F for 25 minutes.
Combine the barley, roasted vegetables, and spinach in a bowl so the spinach wilts slightly.
Dress with the remaining oil and lemon juice, season, and serve warm.
