Preheat grill to medium-high heat.
In a small bowl, combine BBQ sauce, olive oil, minced garlic, paprika, salt, and black pepper. Stir until well combined.
Place chicken breasts on the grill and brush generously with BBQ sauce mixture. Cook for 8-10 minutes per side, or until chicken is cooked through and juices run clear.
Remove chicken from grill and let rest for a few minutes before serving. Serve with additional BBQ sauce, if desired.
Enjoy your delicious grilled BBQ chicken!
