Prepare the Cheese. Slice the cheese into two 1/2-inch thick pieces. Ensure the slices are not too thin to prevent them from melting into the pan.
Briefly run the cheese slices under room temperature water and pat dry with a paper towel.
Coat the Cheese. Spread the flour on a rimmed plate and season with ground black pepper.
Dredge each cheese slice in the flour, ensuring an even coating. Shake off any excess flour.
Pan-Fry the Cheese. Heat the olive oil in a medium nonstick skillet over medium heat until hot but not smoking.
Carefully add the cheese slices to the skillet. Cook until the bottom is golden brown and crispy, about 2-3 minutes.
Flip the cheese slices and cook the other side until equally golden and crispy, about 2 more minutes.
Serve. Remove the cheese from the skillet and place it on a serving plate. Squeeze fresh lemon juice over the hot cheese to enhance the flavor. Serve immediately while the cheese is still hot and melty inside.
Optional: Flambé for a Dramatic Presentation. Once the cheese is golden and crispy, remove the skillet from the heat. Pour 1-2 tablespoons of brandy or ouzo over the cheese. Carefully ignite the alcohol with a long lighter. Allow the flames to burn off, then squeeze lemon juice over the cheese to extinguish any remaining flames.
