Step 1

In a medium bowl, whisk eggs and milk and set aside. Pour panko crumbs into a separate medium bowl and set aside. Dip both sides of bread slice into egg batter. Roll into breadcrumbs a few times until both sides are evenly and fully coated in breadcrumbs. Repeat with remaining bread.

Step 2

Add butter to skillet and turn on the heat. After butter is melted, place bread onto skillet and cook until panko crumbs turn a golden brown. Flip over and repeat with the other side. Remove from pan and set aside. Repeat with remaining bread.

Step 3

Place 2 slices of finished bread back onto skillet. Place a slice of cheese on each one and then place remaining 2 bread slice on top of the cheeses, forming 2 sandwiches. Pressing down slightly onto sandwich, heat both sides until cheese in the center is melted. Remove from heat and serve immediately.
