Preheat your grill to high, clean, then place two small jalapeño peppers on the grill and roast for 5-10 minutes, turning a few times to get a good char on it. Remove from the grill, lower the temperature of the grill to low heat.
Place the jalapeño peppers in the refrigerator to cool. While the peppers cool, in a large bowl add lean ground beef, white onions, parsley, season salt, chopped bacon, and garlic. Remove the jalapeño peppers from the refrigerator, remove stem and seeds if you want to keep the heat to a minimum. Finely chop jalapeños and add to the mix bowl. Mix well, but be careful not to over mix. Make 8 meatballs from the mixture. Once you've made the meatballs begin to flatten them down to hamburger patties. Remember, we are making sliders so you want them small. I like to really flatten out the pattie since it tends to bulk up once on the grill.
Place the beef patties on the grill, cook for 3 minutes on each side. During the last minute of cooking add the pepper jack cheese, and add the King's Original Hawaiian Sweet Rolls to the grill to give them a light toasting. Remove the patties and sweet rolls from the grill. Assemble in the following order: Bottom of sweet roll, beef pattie, tomato slice, ranch dressing, sweet roll top. Enjoy!
