01 - Rinse farro under cold running water. Combine farro, 3 cups water, and ½ teaspoon salt in a medium saucepan. Bring to a rolling boil, then reduce heat to low and simmer uncovered for 25–30 minutes until grains are tender but still have a slight chew. Drain excess liquid through a fine mesh strainer and spread farro on a sheet pan to cool to room temperature.
02 - While the farro cools, dice the English cucumber, halve the cherry tomatoes, and finely dice the red onion. Segment the orange and cut each segment into bite-sized pieces. Chop the fresh parsley, mint, and dill.
03 - In a large mixing bowl, combine the cooled farro, diced cucumber, halved cherry tomatoes, red onion, orange segments, parsley, mint, and dill. Toss gently to distribute ingredients evenly.
04 - In a small bowl or mason jar, whisk together the extra-virgin olive oil, lemon juice, lemon zest, vinegar, honey, Dijon mustard, and a pinch each of salt and freshly ground black pepper until the dressing is emulsified and smooth.
05 - Pour the dressing over the salad and toss gently to coat every component. Taste and adjust salt and pepper as needed. Refrigerate for at least 15 minutes before serving to allow the flavors to meld together. Serve cold or at room temperature.
