Marinate the chicken
Place the chicken pieces in a bowl or zip-top bag. Add 1 cup of barbecue sauce and toss until the chicken is well coated.
Refrigerate for at least 30 minutes. For deeper flavor, marinate the chicken for a few hours.
Cook the bacon
While the chicken marinates, cook the bacon in a skillet over low to medium heat until crisp.
Transfer it to a paper towel-lined plate and let it cool. Break or cut the bacon into slider-sized pieces.
Grill the chicken
Preheat a grill or grill pan over medium heat.
Remove the chicken from the marinade and cook for about 3 minutes per side, brushing with fresh barbecue sauce as it cooks.
The chicken is done when it reaches 165°F in the thickest part.
Slice the rolls
Keep the Hawaiian rolls connected and slice the whole pack in half horizontally.
Place the bottom half on a cutting board or serving tray.
Add the creamy base
Spread mayonnaise over the bottom rolls.
This adds moisture and helps the sliders taste rich and balanced.
Layer the chicken and sauce
Add the grilled BBQ chicken pieces over the bottom rolls.
Brush or spoon a little extra barbecue sauce over the chicken for more flavor.
Add cheese and toppings
Layer the Colby Jack cheese over the chicken.
Add crispy bacon, red onion slices, shredded lettuce, and a drizzle of ranch dressing.
Finish and serve
Place the top half of the rolls over the filling.
Slice into 12 individual sliders and serve right away, or wrap and chill if making ahead.
