I used a mix of Shredded Mild Cheddar Cheese and Mozzarella, but if you want to use casserole cheese or any of your favorite ones.
This dish could be with meat or without. Also, you can use ground sausage, turkey or chicken, it's up to you. Same goes for vegetables. You can use broccoli, for example.
Sage: little goes a long way, but the aroma pulls meat so well together If you do not have any, no problem uses any of your favorite herbs. Pasta: I tried different shapes and all of them work fine such as shells, elbow macaroni, egg noodles, penne, rotini etc.
I hate using canned products, honestly. If I am going to get it, it is usually frozen. But if I am in hurry, yes I use canned shrimp soup, saves time. If you do not wish to use canned mushroom soup than you can make it yourself. It can be in the fridge for 5 days if it is well sealed plus it tastes fantastic. Click here for mushroom soup.
IF YOU DO NOT like mushroom soup you can use cream of chicken, Alfredo sauce, or even marinara (tomato) sauce would be ok -it tastes like lasagna.
