Step 1Wash and drain the farro. In a medium saucepan, cover the farro with 4 cups cold water, then add the sachet of bay leaf and thyme. Bring to a boil. Reduce the heat and simmer. Season with one-half teaspoon salt. Cook until the farro is tender, about 25 to 30 minutes, then drain. Let cool. You should have about 3 cups cooked farro.
Step 2While the farro is cooking, roast the red pepper on a rack over a gas burner over high heat, turning until all sides are blackened, about 10 minutes. Let the pepper stand in a covered bowl until cool, then peel and seed. Cut into medium dice. You will need 6 tablespoons diced pepper. Leftover pepper can be reserved for another use.
Step 3In a medium bowl, toss together the farro, roasted pepper, the peas and the mixed herbs. Add the lemon juice and olive oil and toss. Add three-fourths teaspoon salt, or to taste.
Step 4Let the salad stand 10 minutes for the flavors to blend. Divide equally onto four to six plates and sprinkle with the freshly grated pecorino cheese or ricotta salata.
