Warm BBQ sauce in a small saucepan over medium-low heat. Add pork and warm through. Set aside
Add minced garlic to room temperature butter and combine well. Spread butter on outside of all slices of bread. Turn bread over so unbuttered side is up
Evenly spread mustard on all slices of bread.
On 2 slices of bread, add half of the cheese combination, pulled pork, and pickles. Top with the rest of the cheese
Place other 2 slices of bread on top, mustard side down, so buttered sides are on the outside of both sandwiches
Heat large skillet over medium-high heat. Place sandwiches in skillet, and place heavy-bottomed pan on top of sandwiches to press them down. After 4-5 minutes, check bread. When the bread is a beautiful golden color, carefully flip sandwich and cook other side.
Remove sandwiches from skillet, cut in half (so they are easier to eat). Enjoy!
