Make the bacon if it's not already prepared. You can cook it your preferred way. Cook until crispy and then drain on a paper towel lined plate or bowl, cut into small pieces.
Preheat the oven to 350º. In a medium sized bowl, make the yogurt ranch dressing. Add the yogurt and seasonings, add 1/4 cup of water to thin the sauce out, feel free to add a little more water if needed to thin the dressing out. Taste it and make sure it's to your salted level.
In a bowl, combine shredded (cooked) chicken, the cooked bacon pieces, and a little less than 1/2 cup of ranch dressing. Mix this up and as long as the mixture is moist, do not add any more dressing. If the mixture looks dry, add a little bit more dressing and mix again.
Cut the rolls in half so that you have one sheet of bottom rolls and one sheet of top rolls. *I find it's easiest to cut this way if you take the rolls out of the package and let them sit on the counter to "dry" out for a few minutes. It makes it much easier to slice!
Place the bottom of the rolls in a 9x9 or similar sized baking dish. Using a pastry brush or a spoon, add a thin layer of yogurt ranch dressing to the inside of the bottom rolls. Add the chicken bacon mixture and then sprinkle shredded cheese over the chicken. You can used sliced cheese or shredded, I find that shredded melted better. Add pickled jalapeños if using.
Place the top sheet of rolls over the sliders. Brush the rolls with melted butter and sprinkle with Parmesan & chive. Cover the rolls tightly with foil, place in the oven and bake for 20-25 minutes or until the top of the sliders get a little crispy and browned.
Pull the sliders out, let them cool for a few minutes. Use a sharp knife to gently cut them up and enjoy!
