# How to Make It:
01 - Combine drained tuna, mayonnaise, Dijon mustard, celery, red onion, lemon juice, salt, and pepper in a mixing bowl until thoroughly mixed.
02 - Arrange bread slices on a flat surface. Spread tuna salad evenly over two slices, then layer each with two slices of cheddar cheese. Top with remaining bread slices to form sandwiches.
