Preheat oven to 400 degrees. Cook the bacon, drain the strips on a paper towel. Cut the bacon into bite-size pieces when cool. Combine the Brussels Sprouts, olive oil, garlic, and thoroughly coat them in a large bowl. Bake the Brussels Sprouts for about 20-25 minutes or until tender. Serve with the bacon sprinkled on top with freshly grated Parmesan cheese. Salt and Pepper to taste.
