This is an olive oil based sauce, very easy to prepare and incredibly tasty. You can prepare this meal in literally the same time it takes to boil the pasta
Cook spaghetti in a large pot of salted boiling water until al dente.
Reserve one cup cooking water then drain.
A few minutes before the spaghetti is al dente, add olive oil, garlic and red chili flakes to a saute pan that is large enough to accommodate the pasta once it has cooked.
Cook over medium heat until the garlic starts to turn golden (careful not to burn).
Transfer pasta to the saute pan and toss.
Salt to taste.
If the pasta is dry, add some of the reserved cooking water.
Serve with grated Parmesan cheese and chopped parsley.
