DECADENT CARAMELIZED TUNA PATTY MELTS

Steps:

• For the Thousand Island dressing: Stir together all the ingredients in a small bowl until well combined. Set aside.
• For the universal tuna salad: Open the tuna cans and, using the back of a spoon, press as much of the liquid out as you can. Whisk together the mayonnaise, lemon juice, olive oil, mustard, salt and pepper in a small bowl. Fold in the tuna and stir until incorporated.
• For the patty melt: Stir together the tuna salad and the sauerkraut in a medium bowl, and divide the mixture into 4 equal portions. Using your hands, form each portion into a ball, and squeeze out any remaining liquid.
• Heat the oil in a medium skillet over medium-high heat. Add the balls of tuna, pressing them into flat patties using a spatula. (It's okay if they run into each other.) Cook until caramelized on the bottom, 4 to 5 minutes. Gently turn the patties over, and cook until the other side is caramelized. Transfer the patties to a plate, and cover with aluminum foil to keep warm.
• Spread 2 slices of the bread with 1/2 teaspoon butter on each side, and put them in the skillet over medium-low heat. Top each bread slice with a Swiss cheese slice, and cook until the cheese melts, about 1 minute. Spread 1 tablespoon of the dressing on each cheese slice. Top each with a warm tuna patty and 1 Swiss cheese slice. Top each sandwich with another slice of bread, and butter the outside of each bread slice with 1/2 teaspoon butter. Cook for 1 minute; turn and cook until the bread is toasted and the cheese is melted, another 1 to 2 minutes. Repeat the process to make 2 more patty melt sandwiches. Serve the sandwiches hot with the remaining dressing.
