Step 1

Heat the broiler to high and line a rimmed baking sheet with aluminum foil.

Step 2

Add the tuna, chopped eggs, celery, dill pickles, pickled jalapeños and scallions to a mixing bowl. Mix to incorporate and to break up any large chunks of tuna. Set aside.

Step 3

Add the mayonnaise, mustard and smoked paprika to a small bowl. Whisk to combine. Add the mayonnaise mixture to the tuna mixture and use a rubber spatula to mix until evenly combined. Season to taste.

Step 4

Arrange the bread on the foil-lined baking sheet. Divide the tuna mixture evenly among the slices of bread. Top the tuna with a few slices of tomato. Sprinkle the tomato with salt and pepper. Top the tomatoes with the pepper jack cheese.

Step 5

Transfer the baking sheet to the broiler and broil until the cheese is bubbling and melted, 1 to 2 minutes.

Step 6

Transfer the sandwiches to a cutting board, then slice in half and serve immediately.
