I got this recipe from an old school friend, Jason Crane. He highly recommended it so I had to try it. And - he was right. It is yummy!
1 9-inch pie shell
1/2 yellow or red onion, chopped
3-4 tomatoes, cut in half horizontally, squeezed to remove excess juice, roughly chopped, to yield approximately 3 cups chopped tomatoes
1/4 cup sliced basil
2 cups grated cheese (combination of sharp cheddar and Monterey Jack, or Gruyere or Mozzarella)
3/4 cup mayonnaise
1 teaspoon (or more to taste) of Frank's Hot Sauce (or Tabasco)
Salt and freshly ground black pepper
Preheat oven to 350°F. Place pie shell in oven and cook for 8-10 minutes or longer until lightly golden. If you are starting with a frozen crust, you'll need to cook it a little longer. If you are using a homemade crust, freeze the crust first, then line the crust with aluminum foil and pre-bake it for 20 minutes, then remove the foil and bake an additional 10 minutes.
Squeeze as much moisture as you can out of the chopped tomatoes, using either paper towels, a clean dish towel.
Sprinkle the bottom of the pre-cooked pie shell with chopped onion. Spread the chopped tomatoes over the onions. Sprinkle the sliced basil over the tomatoes.
In a medium bowl, mix together the grated cheese, mayonnaise, Tabasco, a sprinkling of salt and freshly ground black pepper. Spread the cheese mixture over the tomatoes.
Place in oven and bake until browned and bubbly, anywhere from 25 to 45 minutes.
Be sure to check out the website at Simply Recipes for lots of versions of this pie. There are many cheese combos that you can use. I did a mixture of Colby, Sharp Cheddar, and Monterey Jack. Next time I am planning on some Mozzarella.
