This is a simple one pot meal for cooking in the motorhome, and most ingredients you would have on hand, or are easy to come by.
Sometimes we add green peppers and/or red peppers like we did last night. And you can easily substitute cheddar or any other cheese for the mozzerella. And we use whole wheat noodles, which tend to have to cook a little longer.
This is just after adding the noodles. In 20 minutes or so, the noodles will have absorbed the liquid, leaving a nice creamy sauce behind. Yum!
