Horseradish Roast Beef Sandwich on a Pretzel Roll

This recipe is a bit of a treat, not unlike the meatball sandwich from June. But it's super delicious, and well worth it.

I started by caramelizing some onions, and added some chopped mushrooms to it - onions and mushrooms are such an amazing combination. I added a touch of garlic powder and a splash of balsamic vinegar at the end.

Funny story, I tried to get some nice roast beef freshly cooked from the deli at Whole Foods. Apparently, whoever was in charge of the roast burnt it and they wouldn't have any more for a few days. I had a craving, so I had to persevere. Instead I picked up Applegate Roast Beef from the prepackaged aisle instead. It totally worked.

I also added some Yancey's Horseradish Cheddar to the mix, and put it all on a pretzel roll. These pretzel rolls are a great new find. In Texas, they are only available at Whole Foods, but you can also get them online. I highly recommend them. I think that the pretzel bites would be fantastic for Oktoberfest! For ease of sandwich stacking, I chose to scoop out some of the filling on my bread, but the husband did not.

Since my ingredients were cold, I used the toaster to heat it all up - meat and cheese on one side of the bread, and onions and mushrooms on the other. In the photo below, you'll notice that the meat is put on the bread "as is" - for round two I chopped up the beef and it was much easier to eat.

We enjoyed the sandwich with a nice side of fruit salad. Yum!
