Heat your grill at high heat (around 450F) for direct cooking.
Add a cast iron skillet or plancha over the flames. Add the beef and “chop” it up more so it's finely cut.
Once all the meat is cooked and there is no more red in the meat, season with salt, pepper and garlic.
Add your caramelized onions to the meat and mix with the meat.
Make the meat into a shape on the skillet that will fit on your bun, then cover the top with cheese and let it melt.
Add the sliced bun over the pile of meat and then lift it up and into the bun.
Set the cheesesteak down on a platter and repeat for the other cheesesteaks.
Build your cheesesteak with the special sauce, pickles, tomatoes and lettuce.
For extra flavor, wrap in foil and let sit for 1-2 minutes. Slice in half, serve and enjoy!
