Wonderful Donna! This was my very first time making mostaccioli and thought this was a perfect recipe. Only thing I did different was added a little sugar to my sauce mixture and only used mozzarella cheese and no parmesan. Thanks!!

Excellent Dish! My family and boyfriend and his family love this dish! I had a package of ground intalian sausage so used that instead of ground beef. I also just used Ragu Mushroom & Green Pepper spaghetti sauce because I did not have a can tomatoe sauce. It came out perfect! Thank you so much Donna!!!

What a wonderful easy meal.. Made this on a game day and dh told me more than once he liked it :) I also added more cheese than called for, sprinkling some parmesan on top. I also added some garlic and italian seasoning.. This will be made over and over.. Thanks so much Donna for a great, tasty meal..
