First make the sandwich spread by mixing all of the sandwich spread ingredients.
Spread about a tablespoon of the sandwich spread on to one side of the bread.
Then, layer your ham, turkey, pickles, and Swiss cheese on to that slice of bread you put the sandwich spread on. To complete the sandwich, top with another piece of bread.
Repeat this 3 more times to make a total of 4 sandwiches with your ingredients.
Melt the butter, and brush the outer sides of the bread with the melted butter.
Turn on your griddle or panini press and let it heat up according to the manual's instructions. Or let a pan get hot on medium to medium high heat.
Once the pan or cooking device is hot, add your sandwiches to it and cooked until the outside of each sandwich is golden brown, the cheese is melted, and the sandwich filling is heated through. This typical takes me about 3 to 4 minutes. (If you are using a pan, make sure to flip the sandwiches every one to two minutes to ensure both sides get golden brown, and the filling heats through.)
