First off, prepare the red chilies/jalapeños. Slice them in half, and carefully remove as many of the seeds as you can. If you like it super spicy, then leave the seeds in. IF PAN-ROASTING: add a bit of oil to a pan and pan-roast them until they are charred (about 3 minutes, then flip and char on the other side as well). IF BROILING: Pre-heat broiler to 525, then place the cut chilies/jalapeños on a foil-lined baking tray and broil for 3-5 minutes. Remove and carefully flip the chilies/jalapeños over and broil for another 3-5 minutes. Remove from the oven and set aside to assemble onto s'mores.
Make sure the broiler is set to 525.
Place the graham cracker squares on a foil-lined baking tray. I like to use foil as it is easy to clean everything up.
Then place a chocolate square on top of each.
Place a roasted chili/jalapeño on top of the chocolate and then place a marshmallow on top .
Place the baking tray with s'mores under the broiler and let broil for about 4-6 minutes. Keep an eye on the marshmallows as each oven differs and with some 4 minutes could be too long. You just want a golden hue to your marshmallows.
Remove from the oven, top with a remaining graham cracker square and enjoy!
