Cook pasta in salt water as described on the package
Put a thick layer of olive oil in a small saucepan on low heat
Add pressed garlic and a finely chopped chilli pepper. Make sure the oil stays cool enough not to fry the garlic and chilli. It's just to flavour the oil.
Drain the pasta, add the oil, top with too much parmesan cheese
If you want to fancy it up, fry some sliced mushrooms and/or pancetta and add it in.
