- Lay out the 4 slices of whole-grain bread on a clean surface.
- Divide the tuna salad mixture evenly and spread it over 2 of the bread slices.
- Top the tuna salad with a slice of cheddar cheese.
- Layer a lettuce leaf and a few tomato slices on top of the cheese.
Complete and serve the sandwich.
Place the remaining 2 slices of bread on top to close the sandwiches. If you like, slice them in half diagonally. Serve immediately.
TIPFor a tuna melt, you can butter the outside of the bread and grill the assembled sandwich in a pan until golden brown and the cheese is melted.
