These simple sautéed mushrooms work as a quick, weeknight side dish. To turn them into a main course, toss with cooked pasta and a generous handful of Parmesan cheese or fold into an omelette with Gruyère, fontina, or Swiss cheese.
Cook the bacon in a large skillet over medium heat until just beginning to brown, about 4 minutes. Add the mushrooms, garlic, rosemary, salt, and pepper, to taste, and cook, stirring occasionally, until almost dry, 8-10 minutes. Pour in the wine and cook until most of the liquid has evaporated, 30-60 seconds.
