In a medium saucepan, bring the vegetable broth (or water) to a boil. Add the rinsed farro, reduce the heat to low, and cover. Let it simmer for about 25-30 minutes or until the farro is tender but still chewy. Drain any excess liquid and let it cool.
While the farro is cooking, chop the cherry tomatoes, cucumber, red onion, and bell pepper. Place them in a large mixing bowl.
Add the sliced Kalamata olives and crumbled feta cheese to the bowl with the vegetables.
In a small bowl, whisk together the olive oil, lemon juice, dried oregano, and a pinch of salt and pepper to create a dressing.
Once the farro has cooled, add it to the bowl with the vegetables, olives, and feta. Pour the dressing over the top and gently mix until all ingredients are well combined.
Fold in the fresh parsley and taste for seasoning; adjust salt and pepper as needed. Cover the salad and let it chill in the refrigerator for at least 30 minutes to allow the flavors to meld.
Notes
Let the salad chill for at least 30 minutes to enhance the flavors.
