    It was very good but not as good when reheated. I did add more basil & used fresh tomatoes.

    This casserole is a definite keeper! Based on reviews I made some changes: I added a pound each of mild sausage and ground beef, used fresh tomatoes, doubled the onion, used double Italian seasoning instead of basil and oregano and mixed it all together instead of layering. It's a new once a week meal as long as the zucchini, tomatoes and onions from the garden last!

    This was a delicious recipe however the stuffing mix doesn’t seem to say whether you prepare it ahead of time or put it on dry therefore I measured it and put it on dry after baking it and removing it it was still hard and crunchy. I would like clarification as to whether or not it should’ve been prepared ahead of time I will do that in the future other than that the recipe was excellent other than the dry hard crunchy stuffing mix

    Looks very tasty. Wondering on the stuffing mix. Do you mean the box kind or the bag bread cubes you can buy?

    This was divine! I did add a pound of sausage and I used garden tomatoes instead of the canned diced tomatoes. I also used half zucchini and half summer squash. Everyone had seconds on this dish.

    If one enjoys cooked tomatoes, this is a good recipe.

    This recipe is so good and what a great way to use the zucchini from the garden. The only change that I made was using fresh tomatoes from the garden rather than canned tomatoes. I will definitely make this again.
