Prime Rib Sandwiches

My DH and I seldom got to go out to dinner alone while our 3 daughters were growing up. When we did, we made a bee-line for Cask N Cleaver and ordered their Prime Rib Sandwiches. Costco sells a great pre-cooked prime rib or you can cook you own as I do, with the seasonings you prefer. I am partial to a line of spices and seasonings from Penzeys Spices and swear by their Prime Rib Seasoning.

• Ready In: 35 mins
• Serves: 8-10

Ingredients

• 4  lbs  prime rib roast
• 1 (1 ounce) package  au jus mix
• 2  loaves  sourdough bread, sliced
• 3 -4  garlic cloves
• 1  lb butter
• 1  cup parmesan cheese
• 1⁄2 lb swiss cheese
• 1⁄4 cup horseradish

Directions

1. Roast and cool the Prime Rib. Use an electric meat slicer to slice the prime rib roast into very thin slices.
2. Mix Au jus to package directions (I like Lawry's).
3. Grate Swiss cheese and Parmesan cheese or buy pre-grated.
4. Place garlic cloves in a food processor and pulse several times. Add butter and pulse until blended. There will be small pieces of garlic in the mixture.
5. Heat a skillet or electric griddle.
6. Spread garlic butter on both sides of 2 pieces of bread and toast one side.
7. Flip both pieces of bread, and sprinkle with Parmesan.
8. When bottom is toasted, flip bread again, to toast Parmesan to bread. Top with a layer of prime rib and a layer of Swiss cheese.
9. Place one slice of bread on top, (Parmesan should be on the outside of the sandwich) and flip so Swiss cheese is on the bottom and heat until melted.
10. Cut sandwich on the diagonal. Serve with warm Aujus and a bit of horseradish on the side.
