01 - Preheat the oven to 350°F for optional roll toasting.
02 - Heat olive oil in a large skillet over medium heat. Add chopped onion and sauté for 3-4 minutes until translucent. Add minced garlic and cook for 1 additional minute until fragrant.
03 - Place chicken breasts in the skillet. Add chicken broth, smoked paprika, salt, and pepper. Pour BBQ sauce evenly over the chicken. Cover and reduce heat to low.
04 - Simmer covered for 25-30 minutes until chicken is fully cooked and shreds easily. Alternatively, transfer to a slow cooker and cook on LOW for 3-4 hours.
05 - Transfer cooked chicken to a cutting board. Use two forks to shred the meat into bite-sized pieces. Return shredded chicken to the skillet and stir thoroughly to coat evenly with the sauce.
06 - Arrange Hawaiian rolls cut-side up on a baking sheet. Brush with melted butter if desired. Toast in the preheated oven for 4-5 minutes until lightly golden.
07 - Spoon BBQ pulled chicken onto the bottom half of each roll. Top with coleslaw if using. Place the top bun over the filling.
08 - Serve sliders immediately while warm, accompanied by extra BBQ sauce on the side for dipping.
