Step 1:
Preheat the oven to 400°F. Slice the butternut squash lengthwise into 4 planks, each about 1-inch thick, using a sturdy chef's knife. In a small mixing bowl, combine smoked paprika with 2 tablespoons of olive oil; season with kosher salt and freshly ground black pepper.
Step 2:
Warm a large, ovenproof skillet over medium-high heat. Brush the paprika-infused oil evenly over both sides of the squash planks. Place them in the skillet and cook, flipping once, until the squash develops a golden-brown crust in spots, about 3 minutes per side.
Step 3:
Transfer the skillet to the oven. Roast the squash until it becomes tender, approximately 20 to 25 minutes.
Step 4:
Meanwhile, bring a small pot of salted water to a boil. Add the farro and cook, stirring occasionally, until the grains are tender yet slightly chewy, around 20 to 25 minutes. Drain the cooked farro.
Step 5:
In a medium bowl, mix the white and light green scallion parts with the chopped shallot, sherry vinegar, and the remaining 4 tablespoons of olive oil. Allow the mixture to rest for 10 minutes to meld the flavors.
Step 6:
Fold the drained farro, golden raisins, pistachios, and pomegranate arils into the scallion-shallot mixture, stirring to blend thoroughly. Season the salad with salt and pepper according to taste.
Step 7:
To serve, spread a generous spoonful of Greek yogurt onto each plate. Arrange the grain salad on top of the yogurt, followed by a butternut squash plank. Finish with a sprinkle of the reserved dark green scallion slices. Enjoy this dish as a vibrant, satisfying plant-based meal.
