Add the broth and the peas, and bring to a simmer.
Add the butter and whipping cream, and turn the heat down to low.
Gently stir sauce until the butter has melted and the sauce has slightly thickened.
Add the green onions, parsley, basil, and a little of the parmesan cheese and gently stir to combine. Add the remaining parmesan a little at a time, stirring in between each addition.
Taste the sauce, and adjust the salt and pepper to your liking.
Add the pasta to the sauce and toss to combine for 1 to 2 minutes.
Serve immediately with extra Parmesan cheese sprinkled on top.
