First, assemble your ingredients. Then you can entertain yourself while the hotplate take 8 years to boil your water for the pasta.

While you're waiting, you can chop your onions and fry them. Luckily, that will take 8 years too, on the hot plate, so you can finish the pasta and onions a the same time.
When one of those things is done, you can heat up the vegetable broth and pasta sauce, and add the beans and eventually the onions.

Add the pasta and you're done! Delicious and pretty easy!
