Wash the okra in cool water and pat dry
Cut the "cap" stem end off the okra pods then cut them in half lengthwise
Beat the egg whites, salt, pepper, fresh lemon juice and cornstarch together in a large bowl
Add the okra to the bowl and coat the okra well in the egg white mixture
In a large zip top bag shake the masa harina (or corn meal) together with the lemon pepper
Heat the oil over medium high heat (about 350 degrees) in a frying pan
Working in batches shake the okra in the masa harina
Shake off the extra masa and fry the okra for 2 minutes per side until it becomes golden brown
Remove the okra from the hot oil with a slotted spoon and drain on a rack covered with paper towels.
Taste for seasoning and add additional salt or lemon pepper if needed
