Bring the steaks to room temperature before cooking. Put them in a shallow dish and rub both sides of the meat liberally with garlic. Season with marjoram, rosemary, and salt and pepper, to taste. Drizzle with a liberal dose of extra-virgin olive oil and let marinate for 15 minutes.
Preheat a cast iron griddle or large grill pan over medium-high heat. Grill the steaks for 4 minutes on each side for medium-rare. Remove the steaks from the grill to a cutting board and let rest for a few minutes before thinly slicing against the grain.
In a small pot over medium heat, add the beef stock, ketchup, chopped garlic, Worcestershire, dark brown sugar, vinegar and lots of black pepper, to taste. Bring to a boil, then reduce the heat and simmer for 20 minutes for the perfect sloppy sauce. Cook's Note: Try the same sauce recipe atop of thinly sliced grilled chicken breast or thighs for sloppy sliced chickenwiches.
Grate the shallot into a bowl and add the mustard, agave or sugar, and wine vinegar. Whisk in extra-virgin olive oil until well combined. Add the slaw and toss to coat. Season with celery salt, and salt and pepper, to taste.
Pile the sliced meat on the bottom halves of the bread and top each with lots of sauce, slaw and onions and/or hot vegetable relish and pickles. Cover with the top half of the bread and serve.
