Fast French Dip Sandwiches

This sandwich was pinned by a few of my friends on Pinterest and it looked so good so I had to try it. We had this for dinner last night and it was a delicious sandwich. I definitely suggest garlic or horseradish mayo - it really bumps up the flavor. My kids thought the sandwich tasted like the NY Steamer at Firehouse Subs, which is their favorite so it was a huge compliment. It makes 4-5 sandwiches depending on how high you pile the roast beef. The recipe is originally from Chaos in the Kitchen.

Fast French Dip Sandwiches

4 cups beef broth
1/2 onion, cut into rings
1-2 teaspoons minced garlic
1 lb thin sliced deli rare roast beef
1/2 lb thin sliced provolone cheese
4-5 hoagie buns 
roasted garlic or horseradish mayo
butter

In a saucepan combine broth, onion rings, and garlic. Bring to a boil and let boil for about 7 minutes or until broth reduces down.

Meanwhile, cut hoagie buns in half and butter. Place under broiler and bake until just slightly browned on edges. Spread mayo on the bottom buns. Divide roast beef evenly among the sandwiches piling it on top of the mayo. Place cheese slices over the beef. Place under the broiler again and broil until cheese is melted and top bun is browned. Close sandwiches, cut on the diagonal and serve with au jus/reduced beef broth on the side.
