01 - Rinse farro under cold water, then combine with water and salt in a medium saucepan. Bring to a boil, reduce heat, cover, and simmer for 20–25 minutes, or until tender but still chewy. Drain any excess water and let cool slightly.
02 - While farro cooks, toss broccoli florets with 1 tablespoon olive oil and a pinch of salt. Heat a grill pan or cast iron skillet over medium-high heat. Add broccoli in a single layer and cook, turning occasionally, until charred in spots and crisp-tender, 8–10 minutes. Set aside to cool slightly.
03 - In a small bowl, whisk together tahini, lemon juice, olive oil, garlic, cumin, salt, and pepper. Add warm water 1 tablespoon at a time until smooth and pourable.
04 - In a large mixing bowl, combine cooked farro, charred broccoli, cherry tomatoes, red onion, parsley, and mint (if using). Drizzle with tahini dressing and toss gently to coat.
05 - Transfer salad to a platter or individual bowls. Sprinkle with toasted pumpkin seeds and additional herbs if desired. Serve warm or at room temperature.
