In a small bowl, combine mayonnaise, dill, Cajun seasoning, and blue cheese. Set aside.
To a clean cutting board, add the arugula, sliced tomatoes, red onions, Swiss cheese, turkey, salami, 2 tablespoons of the Dill Blue Cheese Mayonnaise, jalapenos, and olive oil.
With a big sharp knife, chop everything as small as possible.
Spoon the mixture inside hoagie buns, sub rolls, sliced bread, or any other bread you would like to use.
