Heat the oil over medium heat; add the onions and saute 5 minutes. Add the garlic, saute until the onions begin to brown. Add the anchovies, crush them with a spoon; add the tomatoes; breaking them up with the back of your spoon; cover and simmer to form a sauce, about 15 minutes. Break the turn up into large flakes; add the the sauce with a little pepper (anchovies and turn are already salty, so do not add any salt); simmer, uncovered for 5 minutes more.
