Broiled Triple-Decker Sandwich: The Munroe Melt

Position an oven rack approximately 6 inches from the heat source and preheat the broiler. Line a baking sheet with aluminum foil.

Place roll on the prepared baking sheet, cut-sides-up. Spread Dijonaise on one half of the roll; top with turkey, Swiss cheese, and ham.

Spread mayonnaise on the other half of the roll; top with roast beef, tomato, and Muenster cheese.

Broil both halves of the sandwich, open-faced, until cheeses melt and begin to bubble and ham begins to crisp around the edges.
