Q&D Veggie sauce

Saute a yellow onion until it's soft. Salt. Add half a pound of mushrooms and continue to fry until the mushrooms are limp. Salt. Add a can of chopped up tomatoes, a big slop of wine, big tablespoon of capers, couple of smashed garlic cloves, ten kalamata olives cut into fourths, about a tablespoon of Thai fish sauce (optional), and whatever herbs you like (mostly I use the big bottle of (dried) "Italian Seasonings" which is, I believe, Thyme, Basil, and Oregano). Boil down to desired thickness stirring occasionally. If it gets too thick, add water (or wine) to revive it.
