This is a quicker version of my basic tomato sauce. I cut several corners in this recipe, without sacrificing too much. Instead of pureeing the tomatoes for a smooth sauce, I leave it chunky. I do not use a knife or cutting board for the preparation (although you could, of course). Rather, I use an egg slicer to slice mushrooms and a garlic press to mince garlic. The sauce is started when the pot of water for the pasta is put on the stove. When the pasta is cooked, the sauce is ready.
