For the Sandwich:

Directions

1

Begin by making the tuna salad. Drain your tuna very well. You can use either tuna packed in oil or packed in water. Add the drained tuna to a small bowl. Add mayo, minced onion, lemon juice, and salt and pepper to taste. Mix very well. Taste for seasoning and set the tuna salad aside.

2

Assemble the sandwich. Slice your baguette open lengthwise. Toast it in the oven at 350 degrees F for about 5-7 minutes, if desired. This creates a crunchier outside.

3

On one side of the split bread, spread your mustard out to a thin, even layer. On the other side, spread the mayonnaise evenly to cover. Layer the cucumber slices in a shingled pattern, topping with the green bell pepper, shredded iceberg lettuce, tomato slices, pickles, and black olives.

4

On the other side, spoon your tuna salad onto the bread. Top the lettuce side with olive oil and vinegar. Top the whole sandwich with salt and pepper to taste.

5

Carefully close the sandwich and wrap it tightly in wax or parchment paper. Slice through the middle of the sandwich with a sharp knife and enjoy warm or at room temperature.
