Preheat oven to 425º and melt butter in a skillet

Once butter has melted, add the onions to the skillet and cook until browned, stirring occasionally

While the onions are cooking, small dice or shred your chicken and mix in enough Smoky Brisket sauce to coat it well

Cut the rolls in half (if you eat gluten-free, I recommend the Against the Grain brand, original flavor)

Spread a light coating of brisket sauce on the bun tops and add grilled onions

Spoon on the brisket chicken, level out, and top with mozzarella cheese

Cook for ~12 minutes until cheese begins to brown on top

Serve and enjoy!
