In a large bowl, combine the ground beef with Worcestershire sauce, kosher salt, and black pepper. Mix gently until just combined, taking care not to overwork the meat.
Divide the meat mixture into 3 equal portions. Form each portion into a loose ball, approximately the size of a golf ball. Do not pack them tightly.
Heat your non-stick skillet or griddle over medium-high heat. Add the canola oil and allow it to heat up until shimmering.
Place the meatballs onto the hot skillet and use a spatula to smash them down into thin patties. Press firmly for about 10 seconds to create that signature crust. Season the top with a pinch of salt and pepper.
Cook the patties for about 2-3 minutes until the edges are nicely browned. Flip the patties, add a slice of cheese on top of each, and cover the skillet for about 1 minute to let the cheese melt.
While the cheese is melting, toast the buns in another skillet or in the oven until golden brown.
Place the cheesy patties on the toasted buns and top with your favorite condiments and toppings.
