In a medium saucepan, bring the water or vegetable broth to a boil.
Add the rinsed farro and reduce heat to a simmer. Cover and cook for 20–25 minutes, or until tender but chewy.
Drain any excess water and let the farro cool to room temperature.
Prepare the Dressing:
In a small bowl or jar, whisk together the olive oil, lemon juice, Dijon mustard, garlic, oregano, salt, and pepper.
Assemble the Salad:
In a large mixing bowl, combine the cooked and cooled farro, chickpeas, cherry tomatoes, cucumber, bell pepper, red onion, olives, parsley, salad greens and vegan feta.
Pour the dressing over the salad and toss gently until well-coated.
Refrigerate for 30 minutes to allow flavors to meld, or serve right away.
Notes
To store: Store leftover farro salad in an airtight container in the refrigerator for up to 3 days. With all the fresh ingredients, this is not a recipe that works well for freezing.
