This recipe is a nice change from your usual spaghetti recipe. You can use bottled sauce and that makes it even easier. There are tons of choices in the jared sauce aisle in the grocery store. Also Publix has it buy one get one free quite often too. So it is a good idea to keep some in the pantry for one of those nights you want something easy. This recipe isn't one of those 30 minute meals but it can be done in less than an hour.
A little fresh parm cheese on top and you are good to go.
