Put the peas, olive oil and tarragon in the bowl of a food processor fitted with a metal blade and pulse until finely chopped, about 30 seconds. Add the cream cheese and process until smooth, about 1 minute. Add the Parmesan, lemon zest and salt and pulse to combine. Transfer the mixture to a bowl, cover and refrigerate until ready to use. Serve with carrot chips.
