There isn't enough I can say about this recipe. I wish I could give it more stars!! I did change a few things due to not having them. I used Newmans Own Olive Oil and Vinegar (a salad dressing) instead of your sauce but it was close enough. I also used sliced american cheese. It was amazing! My mouth is still watering! And as for the mayo..gosh it was heavenly. I did add some garlic powder like a few others suggested which made it even better. When I put it in the oven I was already waiting for it to come out! It smelt great and was so good! I love it so much that I created an account here JUST to review it. Thank you so much for this mouthwatering recipe!
