                                                          The first pasta sauce I can think of is "puttanesca."  This has a tomato base like marinara, but includes a briny olive like kalamata, and perhaps a little red pepper flake for spice.  Another option would be the classic alfredo sauce, which is made with a flour/cream base, melting in a bit of cheese at the end.
