Smash-seared shaved wagyu cheesesteak

Cut the ends off the roll, split it and reheat in a toaster oven until crusty outside and soft in the middle.

Shape the shaved meat roughly to fit the bun and season with salt, MSG and black pepper.

Put it on a really hot griddle and press it down for good contact, edges down, like a smashed burger patty; leave it to brown.

Add the diced onion to the beef fat to soften and brown; season the second side of the meat.

Do not chop yet: let it sit to develop a crunchy crust.

Add the hot pickled peppers to the griddle until softened and caramelizing.

Scrape up the browned meat, melt the cheese over it, then chop and fold with two spatulas until the cheese is gooey and melted in.

Add the rest of the cheese and mix the peppers in with the meat; scrape up the crust and load into the roll.
