Beef and Grilled Cheese Sandwiches with Horseradish Mayonnaise

We had these the other night for dinner...and they were awesome!

----

1/2 cup mayonnaise

1 tbsp Dijon mustard

2 tsp prepared horseradish

8 slices sourdough bread

2 cups arugula

8 slices (or so) of beef brisket (or roast beef if brisket is not available)

8 slices provolone cheese

1/4 cup butter, softened, and divided

Preheat a non-stick skillet or griddle to medium-low heat.

In a small bowl, combine mayonnaise, mustard, and horseradish. Use this spread and make a sandwich with the bread, beef, arugula, and cheese. Make sure you put the spread on each piece of bread.

Spread the butter on one side of each sandwich and drop them in the skillet (butter side down, of course). Butter the remaining side. Cook the sandwiches 4 to 5 minutes per side or until they are golden brown. You know how a good grilled cheese sandwich should look. Eat them while they are hot!
