I prefer to leave off the breadcrumbs because I am not a fan, but overall a very good cold night meal.

To my surprise this turned out much better than I expected. I added some minced garlic, used a cheese blend and substituted fresh parsley for dried, as well as some other healthier substitutes (non-fat milk & wheat pasta) and it was very tasty. I will definitely make it again!
