Spaghetti Carbonara for One

1.) Cook the spaghetti in boiling, salted water according to package instructions. Drain pasta and reserve 1/4 cup of the pasta water.
2.) Add pasta to the same pot over low heat. Add the egg white, peas, and bacon. Stir until the egg white is just set. Season with salt and pepper.
3.) In a separate bowl, combine the egg yolk and parmesan cheese. Vigorously stir this mixture into the hot pasta. Toss well. Serve with more pepper and cheese, if desired. Add a bit of pasta water if the mixture is too sticky.
