1 pre-baked pie shell
Spread 2 Tablespoons or so of any kind of mustard you like on baked pie shell crust.
Place 1 layer of sliced tomatoes in bottom of crust. (I also added some sliced Vidalia onions on top of the tomatoes but you don't have to).
Sprinkle the 1st layer of tomatoes with a layer of cheese..any kind you like. I used a mixture of shredded cheeses like you buy in the store already pre-packaged.
Place another layer of tomatoes on top of that...sprinkle with (onions if you want again) and then another layer of cheese. Work your way to the top of the pie crust.
You end with cheese layer.
For the topping you can mix 1/2 cup of mayo and 1/2 cup of Parmesan cheese..spread over cheese and tomato layers. (You do not have to use this last step ..it is super rich...but it makes it good...but you can just have your last layer cheese or maybe top with bacon bits or something). If you need more you can always increase the mayo another 1/4 cup and same for Parmesan cheese...
Bake in 350 to 375 degree oven for about 15 to 20 minutes..till golden brown and bubbly on top.
Cool slightly so juice will set up some...slice and enjoy!
This is one of the best tomato pie recipes I have ever had or made!
