Bring a large pot of heavily salted water to a boil over high heat. Add pasta and cook according to package instructions. Reserve 1/2 cup of the pasta cooking liquid and drain.
Return pasta to the pot add all the remaining ingredients and toss to combine well. Add the reserved pasta water a little bit at a time until the pasta is glossy and well coated. Taste and add more salt, red chile flakes, or olive oil as needed.
Serve hot, room temperature, or cold. Enjoy!
