Step 1: Prepare the Jalapeños

1. Wash the jalapeños and slice them into thin rounds.
2. Remove the seeds and membranes if you prefer a milder flavor. For extra spice, leave some seeds in.
3. Sauté the jalapeño slices in a small pan over medium heat for 2-3 minutes to soften them slightly. Set aside.

Step 2: Mix the Cream Cheese Filling

1. In a mixing bowl, combine the softened cream cheese, garlic powder, smoked paprika, and black pepper.
2. Stir until the mixture is smooth and well-combined.

Step 3: Assemble the Sandwich

1. Spread a generous layer of the cream cheese mixture on one side of each bread slice.
2. Sprinkle shredded cheddar cheese evenly over the cream cheese layer.
3. Add the sautéed jalapeño slices on top of the cheese.
4. If using bacon, place a strip of cooked bacon on top of the jalapeños.
5. Close the sandwich with the second slice of bread, cream cheese side down.

Step 4: Grill the Sandwich

1. Heat a skillet or griddle over medium heat.
2. Spread butter on the outer sides of each sandwich.
3. Place the sandwich in the skillet and cook for 3-4 minutes on each side, or until the bread is golden brown and the cheese is melted.
4. Press down gently with a spatula to ensure even cooking.

Step 5: Serve and Enjoy

1. Remove the sandwich from the skillet and let it cool for 1-2 minutes.
2. Slice the sandwich in half and serve warm.
