Add a bit of oil and butter in a hot fry pan, and then add the following ingredients:

150 gr. pancetta (cut in pieces – kitchen scissors work really well)
2 onions – sliced

Fry over medium heat for a few minutes or until onions are transparent.

Add:
2 cloves garlic – minced
1-28 oz can plum tomatoes (break them up)
Fresh chopped basil – to taste
2-3 oz white wine
1 dry chili (in jar) – remove when sauce is a bit hot.

Simmer 1 hours then mix together with rotini, rigatoni, penne, or similar pasta.
