Chopped Cheese

Step 1 -In a large pot or skillet over medium-low heat, add the ground beef and cook, while crumbling, until most of the fat has rendered out, about 7-8 minutes. It is ok if some pink remains.

Step 2 -Increase the heat to medium.

Step 3 -Add the onions and the garlic and cook until the onion softens, about 4-5 minutes.

Step 4 -Add the salt, the pepper, and the Worcestershire sauce to the beef mixture and stir to combine.

Step 5 -Transfer the pot from the heat.

Step 6 -On a griddle or a large, clean skillet over medium heat, add the hoagie rolls in batches, cut-sides down, and toast until browned, about 2-3 minutes.

Step 7 -Transfer the rolls, cut-side up, to a plate and repeat until all of the rolls are toasted.

Step 8 -On the same griddle or skillet over medium low-heat, add the beef mixture in 6 equal portions, working in batches, as needed.

Step 9 -Cook the beef portions until heated through, then cover each of the portions with 2 slices of the cheese.

Step 10 -Cook the beef mixtures until the cheese melts, about 2-4 minutes.

Step 11 -Using the side of a metal spatula, roughly "chop" each beef portion to mix the cheese into the beef.

Step 12 -Evenly add 1 tablespoon of the mayonnaise to 1 of the toasted sides of each of the rolls.

Step 13 -Place 1 of the rolls, cut-sides down, on top of each portion of the beef mixture and let them cook for 30 seconds.

Step 14 -Using a spatula, simultaneously flip the beef mixture and the rolls, aiming to keep the beef mixture inside the roll as much as possible.

Step 15 -Add the lettuce and the tomatoes on top of the beef filling layers.

Step 16 -Serve the sandwiches immediately with the potato chips.
