1 large egg, lightly beaten
1/2 cup buttermilk
1/2 cup all-purpose flour, divided
1/2 cup cornmeal
1 teaspoon salt
1/2 teaspoon pepper
3 medium-size green tomatoes, cut into 1/3-inch slices
Vegetable oil
Salt to taste

Combine egg and buttermilk; set aside. Combine 1/4 cup all-purpose flour, cornmeal, 1 teaspoon salt, and pepper in a shallow bowl or pan. Dredge tomato slices in remaining 1/4 cup flour; dip in egg mixture, and dredge in cornmeal mixture. Pour oil to a depth of 1/4 to 1/2 inch in a large cast-iron skillet; heat to 375°. Drop tomatoes, in batches, into hot oil, and cook 2 minutes on each side or until golden. Drain on paper towels or a rack. Sprinkle hot tomatoes with salt.
