Method
Make the tuna salad
- Flake the tuna into a medium bowl.
- Mix in the mayonnaise, celery, red onion, Dijon mustard, lemon juice, salt, and black pepper.
Assemble and cook the melts
- Spread butter on one side of each bread slice.
- Place cheese and one-quarter of the tuna salad on the unbuttered side of four slices.
- Top with the remaining bread, buttered sides out.
- Heat a 12-inch skillet over medium-low heat.
- Cook two sandwiches at a time, covered, for 3–4 minutes per side, until the bread is golden brown and the cheese is melted; repeat with the remaining sandwiches.
Notes
For the best texture, drain the tuna well before mixing. Refrigerate leftover tuna salad or sandwiches in an airtight container for up to 3 days; freezing is not recommended. For a whole-grain option, use whole-grain sandwich bread.
