How to Make a Tuna Melt

1 . Stage

Place tuna into a mixing bowl and lightly break it apart with a fork. Add celery, green onion, capers, mayonnaise, and chile paste. Pinch in small pieces mozzarella and stir to mix. Season with salt and black pepper; refrigerate tuna salad until needed.

2 . Stage

Preheat the oven's broiler. Line a baking sheet with aluminum foil.

3 . Stage

Spread butter generously on both sides of French bread slices.

4 . Stage

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 the oven and turn bread slices over on the baking sheet so the darkest sides are on the bottom.

5 . Stage

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 Cheddar over each sandwich. Dust tops with cayenne pepper.

6 . Stage

Place sandwiches under the broiler and cook until cheese is melted and bubbling, 5 to 6 minutes. Chef John
