Heat oven to 450°F. Cook rice per package directions. On a rimmed baking sheet lined with nonstick foil, season chicken with 1/4 teaspoon each salt and pepper and roast for 15 minutes.  Brush chicken with hoisin sauce and return to oven. On a second rimmed baking sheet, toss snow peas with oil, crushed red pepper, and 1/4 teaspoon salt. Roast until chicken is cooked through and snow peas are beginning to char, 5 to 7 minutes more. Serve over rice and sprinkle with cilantro.
