Here's the link I followed. I didn't use the "cavatini" pasta. I used plain ole ziti...but I think it will be a great rendition. This also appears that it will be a great freezer meal, but we're going to have it for dinner tomorrow, so I'll try freezing the casserole next time.
Here's a picture of the "uncooked" version. I'll report back and let you know how it turned out :p
Picture prior to baking....it comes out like any other
baked pasta dish....brown and bubbly!
**Good news...this is a GREAT dish that is was wildly popular for my family and if truth be told, they did not complain that it didn't have any meat. I think that I am going to make another for the freezer this weekend so we'll have a "fast food" meal. I may even try to find some of the different shape pasta to make it even prettier.
