I made this last night and split it between two 8 X 8 pans. We ate one last night and I froze the other for a late work night. DH will just have to pull it out and bake. DH does not usually like "healthy" dishes that contain veggies, but this one he likes! He went back for seconds so I know it is a keeper. I used whole wheat spaghetti and threw in a handful of shredded carrots otherwise I prepared it just as stated. I will definately make it again.
I just finished making this and now, I have 2 casseroles tucked in the freezer. I used full fat cheese(all I had), and added a tablespoon of canola oil to saute the vegetables in. I was a little worried about the tomatoes and milk curdling but, the sauce came together smoothly! I am looking forward to pulling this out and popping it into the oven on a night when I'm too tired to cook !!!
