Last night I made Spaghetti with Walnuts and Anchovies, because we seemed to have all the ingredients (except the parsley, of course, and the pecorino (but we did have parmesan), and I used angel hair instead of spaghetti).

It was very fast, but didn't taste like much.  Next time I'll add more garlic, maybe some crushed red pepper, or, better yet, just make Spaghetti Aglio e Olio.
