Start by heating the butter in a large skillet over medium heat. Once melted, add the ground beef. Use a spatula to break it apart as it cooks. You want it nice and browned. This process usually takes about 5 to 7 minutes.

While the beef is cooking, sprinkle the kosher salt and black pepper over the meat. Stir it well to distribute the seasoning. This brings out the flavor of the beef and gives it that extra punch.

Once your beef is cooked through, lower the heat to medium-low. Lay the slices of cheese over the meat. Let it melt. Cover it with a lid if you want faster melting. The goal here is to create a gooey, cheesy layer that envelops the chopped beef.

While the cheese melts, take your hoagie rolls or buns and place them in the oven on a low broil for about 2–3 minutes. This step is optional, but toasting the rolls adds a lovely texture.

Now it’s time to build your masterpiece. Spoon the cheesy beef mixture into the toasted rolls. Then, layer on the sliced onions, fresh lettuce, and tomato. Top it with a drizzle of mayonnaise and the dill pickle relish.

Cut your sandwich in half if you’re feeling shareable. Serve immediately, preferably while it’s still warm. Trust me; nothing beats that first bite.
