I think that the last version on the Layered Casserole was the best out of the three different versions.

1. Added the extra ricotta cheese took the sour cream taste away and balanced the cheese mixture out nicely.
2. Using the Prego and milk instead of the tomato sauce gave the meat mixture a lot more flavor.
3. Instead of using pasta I used spaghetti squash which I thought gave the meal more of a rich texture to it, and also combining the spaghetti with the meat sauce brought the casserole together better than having the pasta alone on the bottom.

Overall the only complaint I have for this version would be the presentation was not as great as it was just white on the top from the cheese mixture. One suggestion would be to put a few tablespoons of sauce on the top just to give it a better look. I would rate this version a 9, I will definitely be making it again!
