A unique puree of roasted sweet peppers, cashews and garlic, this sauce is one of our favorite secret ingredients. Last week, we served bowls of Corn Fusili with Sweet Sausage and Red Pepper Sauce to a crowd of hungry kids for lunch. Then the next evening before a dinner party, we topped freshly-toasted crostini with a slice of feta, a smear of Red Pepper Sauce and a drizzle of spicy extra virgin olive oil.
