01 - Rinse the farro under cold water. In a medium saucepan, combine farro, water, and salt. Bring to a boil, then reduce heat and simmer uncovered for 25–30 minutes, until farro is tender but still chewy. Drain and let cool slightly.
02 - While the farro cooks, bring a small pot of salted water to a boil. Add peas and cook for 1–2 minutes (fresh) or 2–3 minutes (frozen), until just tender and bright green. Drain and rinse under cold water to stop cooking.
03 - In a large bowl, whisk together olive oil, lemon juice, lemon zest, honey, Dijon mustard, salt, and pepper to make the dressing.
04 - Add cooled farro, peas, cucumber, radishes, mint, parsley, and scallions to the bowl with the dressing. Toss gently to combine.
05 - Taste and adjust seasoning as needed. If desired, fold in feta cheese and pine nuts. Serve chilled or at room temperature, garnished with extra mint and a drizzle of olive oil.
