1 (6.5 ounce) jar oil-packed tuna, drained
1 tablespoon minced green onion
2 tablespoons finely diced celery
2 teaspoons capers, drained
1 teaspoon Asian chile paste (such as sambal oelek)
2 tablespoons mayonnaise, or more to taste
1/3 cup fresh mozzarella cheese
salt and ground black pepper to taste
2 tablespoons softened butter, divided
2 thick slices French bread
1/4 cup shredded sharp white Cheddar cheese, divided
1 pinch cayenne pepper, or to taste
Place tuna into a mixing bowl and lightly break apart with a fork. Add green onion, celery, capers, chile paste, and mayonnaise. Pinch small pieces from mozzarella cheese into the tuna salad and stir to mix. Season with salt and black pepper; refrigerate tuna salad until needed.
Heat oven’s broiler. Line a baking sheet with aluminum foil.
Spread butter generously on both sides of French bread slices.
Broil buttered bread until golden brown on top, 2 to 3 minutes. Flip
bread slices and broil other side until toasted, 2 to 3 more minutes.
Remove from oven and turn bread slices over on the baking sheet so
the darkest sides are on the bottom.
Gently spread tuna salad onto bread slices using 2 forks. Press the
salad onto the bread and spread tuna all the way to the edges of the
bread. Spread shredded sharp Cheddar over each sandwich. Dust tops
with cayenne pepper.
Place sandwiches under broiler and cook until cheese is melted and bubbling, 5 to 6 minutes.
