Start by heating a large skillet over medium heat. Add 2 tablespoons of the oil. Once it's hot, toss in the thinly sliced onions. Cook them down with a sprinkle of sugar. This will help caramelize them, resulting in sweet, golden goodness. Stir occasionally for about 10-15 minutes until they reach that tender, caramel brown state. Add the minced garlic during the last minute so that it doesn't burn.

Once the onions are done, push them to one side of the skillet. Add the remaining oil to the empty side. Increase the heat to medium-high. Toss in the seasoned, thinly sliced beef. Sprinkle with Worcestershire sauce, cayenne pepper, salt, and pepper. Cook for about 5-7 minutes, stirring until the beef is cooked through and has a nice sear.

While the beef is cooking, let's whip up the cheese sauce. In a saucepan, combine the evaporated milk and cornstarch, whisking until smooth. Place over medium heat and bring it to a low simmer. Gradually stir in the shredded cheese, cream cheese, and other seasoning ingredients. Keep stirring until the cheese is melted and the sauce is creamy.

Grab your hoagie rolls. You can toast them lightly if you wish. Once ready, layer in the cooked beef and onions. Drizzle generously with that glorious cheese sauce.

Cut your sandwich in half if you like. You can serve it with extra cheese sauce on the side. Enjoy with fries or a crisp salad—it’s a classic combo!
