What can be better than something that is real easy, taste really good, can be either a main dish or a side dish? This also offers a wide variety of choices. This is sort of a basic recipe. Don't want onions, leave them out. Want something green, peas are fabulous in this also. Want mushrooms, add them. Want to try a cream soup besides the good old stand by cream of mushroom, well here is an easy pallet to try that out. I usually chop the veggies and sausage as I build each layer. If you want to use a raw meat product, you should cook it first. Don't have Italian seasoning, leave it out, or substitute what you have or like instead. This is so versatile, easily changed to fit your likes.
