Whisk eggs and milk together in a bowl and set this egg wash aside. Combine the flour and meat seasoning in another bowl and set aside. Heat the oil in a heavy 14-inch cast iron skillet over medium heat to 350 degrees. Use a deep frying thermometer to check temperature. The oil should pop loudly when a drop of egg is dropped in. Dip each of the first 4 cutlets in the egg wash mixture. Dredge them in the flour, then dip them back into the egg wash, and very gently place them in the hot oil. As you carry them 1 at a time from the egg wash to the skillet, hold a plate under them to catch the dripping egg wash. There'll be a regular explosion of noisy oil popping. Cook for 3 to 5 minutes, until breading is set and golden brown. Gently turn them with a long handled meat fork or long metal tongs. Be careful. Cook another 3 minutes. Carefully remove them from the skillet and drain on a platter lined with paper towels. Let oil reheat and repeat process for other 4 cutlets.
