Prepare the BBQ ranch by mixing your homemade ranch dressing with 2 tablespoons of BBQ sauce per cup.
If making homemade shoestring onions, slice the onions thin and soak them in buttermilk for one hour. Then, toss with seasoned flour and fry in 350°F oil until golden and crispy. About two minutes per batch.
Preheat the grill for medium-high heat and season the patties with salt and pepper. Place the patties on the grill over direct heat, flip often and cook to just below desired internal temperature. After the last flip, top the patties with cheese, move them to indirect heat, and let the cheese melt. About one minute.
While cheese is melting, toast the buns. Then, add BBQ ranch on the bottom bun.
Place the cheese-topped patty on the bun, add the pulled pork, then top with crispy onions and nestle the jalapeños into the onions.
Finish with a light drizzle of BBQ ranch, add the top bun, and press gently. Serve immediately.
