Start sautéing 6 slices of bacon cut into 1 inch pieces. Coarsely chop one medium onion. Sauté these for a while until the bacon begins to brown and the onions soften. Add about a teaspoon of chopped garlic. Add some fresh ground pepper.
Continue to cook this until the pasta is done. Take a half a cup or so of the pasta water and add it to the pan. Drain the pasta and add it to the pan. Mix it all up and serve it with parmesan cheese on top.
