Preheat a griddle or a large skillet over medium heat.
In a small bowl, mix together the softened butter and 2 teaspoons of Revolution Barbecue Nashville Hot Chicken Rub until well combined.
Lay out the slices of bread on a cutting board. Spread the butter mixture on one side of each slice of bread.
On four of the slices of bread, layer 2 slices of American cheese and a few slices of deli chicken or turkey. If desired, add a few pickle chips on top. Then, flip over the remaining four slices of bread and place them on top of the cheese and chicken, with the buttered side facing up.
Place the sandwiches on the preheated griddle or skillet. Cook for 2-3 minutes per side or until the bread is golden brown and the cheese is melted.
Serve the sandwiches immediately, while still warm and gooey.
