Cook pasta according to the package directions. Drain the pasta. Keep it warm while you make the rest of the recipe.
Using a 10-inch nonstick skillet melt the butter until it's sizzling in the pan. Add the mushrooms to the pan. Cook over medium-high heat 2-3 minutes, or until the mushrooms are tender.
Add the green beans, continue cooking 2-3 minutes or until the green beans are tender.
Add the chicken broth and garlic to the pan; cook 1-2 minutes or until heated through.
Remove from the pan from the heat. Add the cooked pasta to the skillet; toss the pasta to coat it. Sprinkle the ingredients in the pan with grated Parmesan Cheese. Serve immediately.
Notes
If you like you can add the green beans to the pasta that's cooking when the pasta has about 3 minutes left to cook so you don't dirty another pan.
