Combine cornmeal and salt. Dip okra in buttermilk; dredge in cornmeal mixture. Pour peanut oil to a depth of 2 inches into a Dutch oven or deep cast-iron skillet; heat to 375°. Fry okra, in batches, 2 minutes or until golden, turning once. Drain on a wire rack over paper towels. Arrange lettuce leaves on a serving platter; top with tomato, onion slices, and bell pepper.
