Put a pot of water on to boil and add some salt. When it comes to a boil, stir in the pasta and cook according to the package directions.

Meanwhile, heat the olive oil in a skillet and cook over medium low heat until golden.

Add the beans and their liquid to the garlic and stir.

Stir in the tomato sauce and water (add water to the can to get all the tomato sauce out!). Bring to a low simmer and cook about ten minutes.

When the pasta is done, drain it and stir into the bean mixture. If it is thicker than you like, stir in a bit more water.

Add the fresh parsley and serve with grated Parmesan cheese. You can also add some dried red pepper flakes.
