01 - Preheat the oven to 425°F. Line a baking sheet with parchment paper.
02 - In a large bowl, toss the eggplant, red bell pepper, and cherry tomatoes with 2 tablespoons olive oil, sea salt, and black pepper. Spread evenly on the prepared baking sheet.
03 - Roast for 25–30 minutes, stirring halfway, until the vegetables are golden and tender.
04 - Rinse the barley under cold water. In a saucepan, combine barley, water or vegetable broth, and 1/2 teaspoon salt. Bring to a boil, reduce heat, and simmer uncovered for 25–30 minutes, or until tender. Drain any excess liquid and set aside.
05 - In a small bowl, whisk together tahini, lemon juice, olive oil, garlic, maple syrup or honey, and salt. Gradually add water, 1 tablespoon at a time, until the dressing is smooth and pourable.
06 - Divide cooked barley among four bowls. Top with roasted vegetables, cucumber, and red onion. Drizzle generously with tahini dressing.
07 - Garnish with parsley or mint, feta cheese, and pine nuts or almonds as desired. Serve immediately or at room temperature.
