Pastrami on Rye

Prepare the Bread

• While the pastrami is steaming, lay out the 8 slices of rye bread on a clean work surface.
• Spread a generous layer of spicy brown mustard on one side of each slice of bread.

Assemble the Sandwiches

• Divide the hot, steamed pastrami evenly among 4 slices of the mustard-spread bread, piling it high for an authentic deli-style feel.
• If using, place a slice of Swiss cheese on top of the hot pastrami; the residual heat will begin to melt it.
• Place the remaining 4 slices of bread on top, mustard-side down, to complete the sandwiches.

Grill the Sandwiches

• Wipe out the skillet used for the pastrami. Lightly spread the softened butter on the outer sides (top and bottom) of each assembled sandwich.
• Place the sandwiches in the skillet over medium heat.
• Grill for 2-3 minutes per side, until the bread is golden brown and crisp, and the Swiss cheese (if using) is fully melted. Avoid pressing down on the sandwich.

Serve

• Remove the sandwiches from the skillet and let them rest for one minute. This allows the fillings to set slightly.
• Using a sharp serrated knife, slice each sandwich in half diagonally.
• Serve immediately with a crisp, whole dill pickle on the side for the classic deli experience.
