PS there are many great sauces for pasta...using fish, meat, veg and/or cheese. See article in bon appetit magazine July 2015 called something like "85 best non-tomatoes sauces for pasta"
Hazan's recipe has certainly proved popular, though not a favorite of mine, but if you like a lot of butter could be a good choice. There are a lot of other sauces combining butter with a few, usually strong flavored, ingredients such as garlic, clams, various herbs- they do tend to be pretty easy.
Google it and you will get more replies than you could read in a lifetime. A search of any recipe site- this one, for example- will net you hundreds of recipes. Narrow it down-say to tomato sauces- and you will still have a baffling array. So the question isn't really answerable- you'd have to refine it a lot to have any hope.
