# How to Make It:
01 - Combine drained tuna, mayonnaise, Dijon mustard, celery, red onion, lemon juice, salt, and pepper in a bowl. Mix until well blended.
02 - Arrange bread slices on a flat surface. Spread tuna salad evenly over two slices, then layer each with two slices of cheddar cheese. Cover with remaining bread slices to form sandwiches.
03 - Spread softened butter on the outsides of each sandwich, covering one side of each bread slice.
04 - Preheat a nonstick skillet or griddle over medium heat.

06 - Flip sandwiches and cook the other side for an additional 3 to 4 minutes, until golden and cheese is melted.
07 - Remove sandwiches from skillet, slice in half, and serve immediately while hot.
