Step 1

In a medium bowl, mix together the drained tuna, mayonnaise, red onions, pickles, salt, pepper, parsley, and lemon juice. Stir well to combine.

Step 2

Butter one side of each slice of bread, about a half tablespoon on each slice. Flip the bread over, butter side down.

Step 3

Take three of the bread slices and divide the tuna mixture evenly between them. Then top each with about a 1/3 cup of shredded cheddar. Top with the remaining sliced of bread, butter side up.

Step 4

Heat a large skillet over medium heat. Once hot, add the sandwiches to the skillet, making sure your bread slices have the butter on the outside so the bread crisps. You made need to work in batches depending on the size of your skillet.

Step 5

Cover the sandwiches in the skillet and heat until the butter on the top slice melts and the grilled side is golden brown. About 3 to 5 minutes. Then carefully flip the sandwich over and grill the other side for an additional 3 to 5 minutes.

Step 6

The sandwich is done when the cheese has melted. Remove from the skillet and let rest a minute or two before slicing in half. Enjoy!
