Preheat the oven to 350˚F. Line a sheet pan with parchment paper with edges extending over the edges of the pan.
Combine the oil, sugar, garlic salt, Italian seasoning and pepper in medium-size bowl and stir. Add the tomatoes and gently stir to coat. Tip the tomatoes out onto the prepared pan and roast in the oven for 25-30 minutes, until most of the juice has been evaporated. Remove and allow to cool while you prepare the rest of the salad.
While the tomatoes are roasting prepare the farro.
For the farro:
While the tomatoes are roasting prepare the farro. Combine the chicken broth, apple juice, bay leaves and kosher salt in a medium-large pot and bring to a boil. Add the farro and cook for the time indicated on the farro package (see notes on types of farro in the post above). If the liquid level gets low, add some water to keep liquid above the farro.
When the farro is done, drain it well, drizzle with a small amount of olive oil and stir. Set aside.
For the dressing:
Combine all ingredients in a small jar with a tight-fitting lid and shake well. Shake again before adding to the salad.
For the salad:
Combine the cooked and drained farro with all of the diced veggies, half of the olives, the herbs and half of the crumbled Feta. Stir to combine. Add 3-4 tablespoon of the dressing and stir again. Taste and add more salt and more dressing, if desired.
Gently stir in half of the tomatoes then transfer the farro mixture to a serving platter or bowl. Top with the remaining tomatoes, olives, Feta and the pine nuts. Garnish with additional fresh herbs sprigs and/or leaves, if desired.
