Instructions
Prep the Brisket
If using leftover brisket, warm it up in a small saucepan with a little bit of BBQ sauce to keep it moist.
Butter the Bread
Spread softened butter on one side of each bread slice.
Layer the Goodness
Place one slice of bread butter-side down on a skillet over medium-low heat. Sprinkle half the cheese, then evenly distribute the brisket and caramelized onions. Drizzle with BBQ sauce and Dijon mustard if using. Top with the remaining cheese and the second slice of bread, butter-side up.
Grill to Perfection
Cook for 3-4 minutes on each side, pressing down lightly with a spatula. Flip carefully once the bottom is golden brown, and cook until the cheese is fully melted.
Serve and Devour
Remove from the skillet, let it rest for a minute, then slice in half and dig in!
