Balsamic Mushroom Pasta

Bring a large saucepan of water to a boil. Add spaghetti and cook according to package directions. Drain.

Meanwhile, heat oil in a large skillet over medium heat. Add onion and cook, stirring, for 2 minutes. Increase heat to medium-high. Working in batches, add mushrooms and cook, stirring, until all the mushrooms have softened and lightly browned, 8 to 10 minutes. Add garlic, thyme, salt and crushed red pepper to taste; cook, stirring, for 1 minute. Add broth, wine and vinegar; bring to a simmer. Cook, stirring occasionally, until the liquid is reduced by half, about 5 minutes. Add the cooked spaghetti to the pan, tossing to coat. Remove from heat; stir in nutritional yeast and sprinkle with parsley.
