Place the peppers on a baking sheet with the cut side facing down, place on the top shelf in the oven and broil until the outer layer of the skin has blackened, about 8-14 minutes.
Place the peppers in a zip-lock bag or other sealable container, seal, and let them cool until you can handle them, about 20 minutes, before pinch off the blackened skins.
Butter the outside of each slice of bread and spread the cream cheese on the inside. Sprinkle half of the cheese on the cream cheese of one slice of bread, top with the jalapenos, bacon, crumbled tortilla chips, the remaining cheese and finally the other slice of bread.
Grill in a pan, preheated over medium heat, until golden brown on both sides and the cheese has melted, about 2-4 minutes per side.
