Preheat a large flat skillet or griddle over medium heat.
Flake the tuna inside a medium-sized bowl then add the mayonnaise, minced pickles, and steak seasoning and stir to combine. Butter one side of each slice of bread then flip two over and top each with half the tuna mixture. Add a slice of cheese then cover with the remaining slices of bread, buttered-side up.
Place the sandwiches onto the preheated skillet or griddle then cook until golden brown on the bottom. Flip then cook until the second side is golden brown and the cheese has melted. Remove sandwiches to plates then slice and serve.

Feel free to use relish vs mincing the pickles for an even faster recipe.
