Preheat oven to 425 - 450 degrees. Put oil in cast iron skillet and heat in oven enough for okra to sizzle. Meanwhile, slice okra into bite-sized pieces. Chop potatoes and add to okra. Sprinkle meal on potatoes and okra to coat. Add salt and pepper, to your taste. Let okra/potatoes set for a few minutes. Some moisture that comes from the veggies will help the meal adhere to the okra/potatoes. Stir a couple of times to better coat. Add okra/potatoes to hot oil, cook in oven until tender and crispy, about 20 minutes. Toward the end of cooking and the okra and potatoes are getting tender, if okra/potatoes are not browned and crispy enough for you, turn up heat and cook for a few more minutes, not long or it will burn. With a slotted spoon, remove okra from skillet and drain on paper towels. Immediately season with salt and pepper.
