If you haven't checked out the Budget Bytes blog, do it. She doesn't have calorie counts up on her recipes, but It is easy enough to track the components of the dishes. Also, there comes a time when you can look at a recipe and know that it is healthy. Her recipes are all healthy.
This was like a healthy grown up version of hamburger helper. I wouldn't really call it "creamy" though. It was easy and delicious. DH and I both loved it as is, no changes. However, even with the mild version of Rotel, the girls complained that it was spicy. Next time that I make it (and there will be a next time), I think I'll use Italian styled tomatoes instead.
Edited to Add - It was like hamburger helper in that the pasta cooked with the other ingredients in the skillet and was super convenient.
