Reuben Nachos

Preheat the oven to 350 degrees F (175 degrees C).

Mix mayonnaise, ketchup, sour cream, relish, red onion, Dijon mustard, and garlic salt together in a small bowl until well blended. Set aside.

Layer 1/2 of the tortilla chips in an even layer on a baking sheet. Top with 1 cup Swiss cheese, 1/2 cup Cheddar cheese, and 1/4 teaspoon dill. Repeat layers on top.

Bake in the preheated oven until cheeses are melted, about 5 minutes. Remove from oven. Set an oven rack about 6 inches from the heat source and preheat the oven's broiler.

Top nachos evenly with corned beef and sauerkraut. Broil until heated through, 1 to 2 minutes. Top nachos with the mayonnaise sauce.
