Preparation:
1. Trim and peel the eggplant; cut into 3/4 inch cubes. Toss the eggplant with the salt in a large bowl and let stand, tossing occasionally, until the eggplant exudes about 3 tablespoons liquid, about 30 minutes. 2. Drain the eggplant in a colander and rinse thoroughly under cold running water. Squeeze the eggplant with your hands to remove as much liquid as possible; drain on paper towels. 3. Beat the eggs with a few drops of water in a mixing bowl until thoroughly blended. Add the eggplant and toss until coated. Turn the eggplant cubes into a colander and shake to remove the excess egg. Place the breadcrumbs in a second mixing bowl, add the egg-coated eggplant and toss with dry hands until the eggplant is coated with crumbs, pressing lightly to make sure they stick the eggplant. Transfer the cubes to a wire rack to set the coating. 4. Heat the oil in a heavy large skillet over medium heat until a coated eggplant cube dropped in the oil gives off a lively sizzle. Add half the eggplant and fry, turning as necessary, until golden brown on all sides, about 2 minutes. Remove to paper towels with slotted spoon and repeat with the remaining eggplant. 6. Heat the oven to 450 degrees. 7. Meanwhile, heat a large pot of generously salted water to boiling over high heat. Stir in the rigatoni and cook, stirring frequently, until the pasta is tender but firm, about 12 - 14 minutes after the water returns to a boil. 8. Reserve 1/2 cup of the boiling liquid, then drain the pasta in a colander, shaking to remove excess water. Return to the pot, add the tomato sauce and reserved cooking liquid. Heat over medium heat to simmering. 9. Transfer to a 2 inch-deep 2 quart baking dish. Scatter the eggplant over the top and sprinkle with cheese. Bake until the sauce is bubbling and the cheese is melted, about 10 minutes. Serve very hot.
