Cut the 0.5 lb bacon into 1/2 inch pieces and add to a large skillet.
Cook over medium heat until the bacon is mostly cooked through, but not completely crisp (it will continue cooking when the mushrooms are added).
Add the sliced mushrooms, and continue to cook for 5-10 minutes until the mushrooms are soft and starting to lightly caramelize, and the bacon is fully cooked.
Meanwhile cook the 3/4 lb spaghetti to al dente, according to package directions.
Turn the heat under the skillet to low, and add the 3-4 Tbsp balsamic vinegar to the pan. Mix everything together, scraping any browned bits from the bottom of the pan.
Add the cooked pasta to the skillet, and toss together with the grated 1/2 cup grated Parmesan cheese, handful fresh sage leaves, sliced thinly, and 1/2 tsp red pepper flakes. Season with salt and fresh cracked black pepper.
Depending on how much fat has rendered from your bacon, you probably wont need additional oil, but if your spaghetti seems at all dry, add a little olive oil or a splash more balsamic vinegar.
Serve immediately with more shredded parmesan, if desired.
