Do you have olive oil or butter? You have sauce.

I have very small bottles of wine, decanted when we opened two different wines, if you have wine you have sauce.

Soy sauce and butter is pretty good for a sauce, miso butter is even better.

I dunno what your pantry holds but I think here we always have some way to make pretty good pasta of some sort. My kids live spaghetti fried in chili garlic paste.
