If you're using mayo, smear it on one side of each bread slice.

Split the cheese evenly between 2 bread pieces. Place another bread slice on each sandwich to seal the deal.

Grab a shallow bowl and beat eggs and milk together. Season with salt and pepper. In another shallow bowl, combine flour (and panko, if using) with a bit of salt and pepper.

Line a plate or small baking sheet with a piece of parchment paper, then keep it close by.

One sandwich at a time, dunk each into the egg and milk mix, making sure it's covered on all sides. Next, roll it around in the flour mix until fully coated. Place each coated sandwich on the parchment-lined plate, repeating the process for the second one.

Pop the coated sandwiches into the fridge for 20 minutes to firm up.

Once 20 minutes pass, heat the oil in a cast iron pan or dutch oven. You'll need about an inch of oil depth.

Carefully place the sandwiches into the hot oil using a spatula. Fry for 2 minutes until golden, then flip and do the same on the other side.

Move sandwiches to a cutting board. Use a serrated knife for a clean cut. Start slicing until you hit the cheese layer, flip the sandwich, and cut again carefully. Serve while still hot and enjoy each bite!
