Boil a large pot of water and cook the pasta according to package instructions. About 2 minutes before the pasta is finished, add the peas to the boiling water as well. Drain together and set aside. In a small saucepan, melt the butter and then stir in the lemon juice. Add the half & half, salt, pepper, dried basil and most of the Parmesan (set a little aside to sprinkle on top of finished dish). Stir to combine and cook over low-medium heat for a few minutes to heat through. Combine pasta/peas mixture and sauce in a serving dish and toss until pasta is coated in sauce. Serve with reserved Parmesan sprinkled over the top.
