Here is the Panini recipe you asked for. Enjoy, and let me know if you have any questions!

Filet of Beef Panini with
Dijon Mustard Horseradish Sauce

THE PANINI
1 loaf 7 Grain Bread
Rare to Medium Roast Beef (see roasting instructions below)
Dijon Mustard Horseradish Sauce (see recipe below)
1 bunch Arugula
1 Panini Maker

TO ROAST THE BEEF
3 to 4 pound beef tenderloin
1/4 - 1/2 cup butter
Cracked black peppercorns
Salt to taste

Preheat oven to 450 degrees. Smear tenderloin with butter until it has a nice coating on it. Then sprinkle and kind of mash in peppercorn (sparingly, as they are pretty strong!). Next sprinkle with salt.

Place on a baking sheet and roast in the oven for about 20 to 25 minutes. Remove from oven and place on a cutting board; tent with a piece of aluminum foil to rest for about 15 minutes or so. Depending on how rare you want it, a meat thermometer should read 140 to 160 degrees for rare to medium rare. And again, everyone’s oven’s heat differently, so what works for 20 to 25 minutes for one oven, may only be 15 to 20 minutes for another.

If you don’t want to go through this roasting process, then by all means, purchase some medium rare roast beef at the deli counter of your local market. It will work out fine!

DIJON MUSTARD HORSERADISH SAUCE
4 tablespoons mayo
1 tablespoon good Dijon Mustard
1 to 2 teaspoons prepared Horseradish
1/2 teaspoon lemon zest
juice of one small lemon

Place all ingredients in a bowl, as listed above, and mix well. Set aside.

PANINI ASSEMBLY
Place 2 slices of 7 grain bread (or the bread of your choice) on a work surface. Smear a healthy amount of Dijon Horseradish sauce on each side of the bread. Place approximately 3 to 4 slices (depending on the thickness of slices) on one side of the bread. Place 3 to 5 leaves of Arugula on top of meat.

Close both halves together, and place in Panini maker. This should only take about 3 to 4 minutes on each side to heat through. If you don’t want to flip them, then give them about 5 minutes to heat.

And if you want added luxury, you could also place on the roast beef, crumbled Gorgonzola. That would be excellent!

Enjoy!
