In a small mixing bowl, make the cream cheese mixture: Combine the cream cheese, chopped jalapeños, and garlic salt.

On a cutting board or flat surface, lay out four slices of bread and top each with one slice of cheese.

Divide the jalapeño filling onto each sandwich and spread out evenly to the edges.

Cut the slices of bacon in half and place onto the four sandwiches over top of the jalapeño filling.

Add the cheese slices on top of the bacon, and then place the remaining slices of bread on top.

Preheat flat top Blackstone Griddle on medium heat.  With an electric Blackstone griddle, set the dial to 400°F.

Spread butter onto the outward-facing sides of the bread on each sandwich.

When the Blackstone Griddle is hot, place the assembled sandwich so the bottom buttered layer of bread is on top of the Blackstone Griddle flat top grill.

Cook for about 1 to 3 minutes until the buttered bread is golden brown. Use a lid to help with the cheese melting process.  Make sure to keep an eye on the cheese sandwich so that it does not get over done and burn the bread.

Using a spatula, flip the Blackstone grilled cheese and grill the other side until golden brown and the cheese is melted.

Make sure the cheese is fully melted. Remove from the hot flat top griddle when done and serve immediately.

Cut the sandwich in half and serve with your favorite tomato soup or chips!
