This is a dish I invented to try and get my picky-eater son to eat something other than macaroni and cheese, hotdogs, or hamburgers! He always thought regular marinara sauce was too "strong tasting"....I think it is just too acidic for him. However, he loves cheese and loves italian sausage. Much to my surprise, I have found that I love this dish as well. I prefer to make the sauce myself, but if you are pressed for time, substitute your favorite pre-made sauce and just add the italian sausage and cream. If you aren't a fan of italian sausage, substitute 1/2 the sausage for ground beef or ground turkey. The rosemary is optional. I like it, but some don't like the taste. If you don't have a picky eater, I would add some mushrooms and possibly some bell peppers. I think those would be nice with the dish.
