To cook the farro, rinse the farro in a strainer and add to a large saucepan or small stockpot. Cover with vegetable stock, bring to a simmer, and cook for 20 minutes.
While the farro is cooking, toss the diced squash with olive oil, salt, and pepper. Roast in the preheated oven for 20 minutes. Remove from the oven and allow to cool.
To assemble the salad, drain the farro and let cool for a few minutes. In a large bowl, combine the farro, squash, persimmon, and pomegranate seeds. Toss with enough dressing to coat lightly, then season to taste with salt, pepper, and scallions.
