1. Place farro in a medium bowl. Add enough water to cover; let soak 20 minutes. Drain. Meanwhile, bring a medium pot of salted water to a boil over high heat; add drained farro and cook until tender, about 20 minutes. Drain and transfer to a large bowl. Add lemon zest and toss to combine; set aside to cool.

2. In a small bowl, whisk together lemon juice and 1/2 cup ricotta salata. Add olive oil in a slow, steady stream, whisking constantly to emulsify. Season with 3/4 teaspoon salt and pepper. Add brussels sprouts, radicchio, pear, carrot, and fennel to bowl with farro. Add lemon juice mixture and toss to combine. Add parsley, mint, and remaining 1/2 cup ricotta salata. Toss to combine and season with salt and pepper; drizzle with additional olive oil or lemon juice, if desired.
