Roast Beef Sandwich

Roast Beef Sandwich
Panera Bread Recipe

Serves 4

6 tablespoons stone-ground or Dijon mustard
6 tablespoons freshly grated or prepared horseradish
1 cup mayonnaise
1 Panera Bread Sourdough baguette
thin slices of lean roast beef

Stir the mustard and horseradish into the mayonnaise until well-blended. Taste and add more mustard or horseradish, if you prefer. Set aside for 20 minutes to allow the flavors to blend.

Cut a Sourdough baguette in half horizontally. Place it cut side up on a baking sheet and broil, watching carefully, for 1 to 2 minutes, until it is toasted to your specifications. Spread the horseradish-mustard sauce on both sides of the toasted bread, then add lettuce, sliced onions and tomatoes. Pile on thin slices of roast beef, reassemble the baguette, and cut into sandwich servings.

NOTES
You can make it an Asiago Roast Beef Sandwich by adding smoked cheddar cheese, lettuce, tomatoes, and red onions on  Asiago Cheese Demi.
