3. Assemble the sandwiches
Brush one side of each slice of bread.
On the unbuttered side:
Spread bang-bang sauce
Add cooked beef
Add bacon
Add cheese
Top with another slice of bread (butter side out).
4. Grill to crispy perfection
Preheat a pan or grill over medium heat.
Cook the sandwiches for 3-4 minutes on each side, pressing gently, until the bread is golden brown and the cheese is completely melted.
5. Rest and cut
Let stand for 1 minute, cut in half, and serve hot.
