I did something recently that I rarely do. I ate a sandwich with fake cheese. We have been traveling for a baseball tournament this past weekend. We were in a relatively remote part of Kentucky.
Our tournament was held in this multi-field baseball park that was impressive. However, when it came to food, there was nothing to be had. The concession stand had a measly selection, and what was worse, the price of their food increased as the day wore on. The closest meal to be had was the one nearby fast food restaurant. And that's where I had the fake cheese.
There is certainly a place for fake cheese. I cannot watch an MLB game without my nachos and cheese. But for the most part, I prefer to make my own, homemade cheese sauce. Homemade cheese sauce tastes amazing on baked potatoes or these cheese steak fries, and it tastes especially good on a roast beef sandwich!
This roast beef sandwich recipe is a little on the gourmet side. Deli roast beef is topped with sautéed mushrooms and sweet caramelized onions. I like to pile on the mushrooms and onions; of course your tastes might be different; adjust accordingly.
Also, a note on the onions: Caramelized onions are incredibly easy to prepare. If you cook onions long enough, they naturally become golden in color and sweeten as they cook. You could add a splash of vinegar (red wine, cider or balsamic) if you want to counteract a little of the natural sweetness, or you could intensify the flavor and stir in a little brown sugar instead. Either way, you win.
The cheese sauce starts with a basic roux; which is butter, flour, and milk that is whisked until smooth. I added shredded cheddar cheese, but you could easily substitute your favorite cheese (I see pepper jack in my future). Whatever cheese you use, I hope you enjoy this sandwich!
