Slice 2 fresh, garden tomatoes and put on a sheet lined with paper towels. Sprinkle with salt and set aside.
In a tart pan, line with pie crust (either home made or store bought). Line the pie shell with foil and bake at 450 for 5 minutes. Remove foil and bake another 8 minutes. Remove from oven.
In a pan, saute 1 medium onion sliced and two garlic cloves chopped until soft and lightly browned. Spread this mixture on the bottom of the pie shell.
Top with 1 cup (more or less) of sliced or grated mozzarella cheese. Top the cheese with the sliced tomatoes. Chop up 6 or 7 basil leaves and sprinkle on top of the tomatoes. Bake at 350 degrees for about 35 minutes. Remove from oven, let sit 10 minutes. Then slice and serve!
