Heat the oven to 425°F and season the sirloin with salt and black pepper.
Heat the olive oil in an oven-safe skillet over medium-high heat and brown the roast for 2 minutes on each side.
Roast for 18 to 24 minutes until the center reaches 145°F, then transfer it to a board and rest for at least 3 minutes.
Pour the broth, Worcestershire, soy sauce and thyme into the skillet, scrape the browned bits and simmer for 8 minutes.
Toast the split rolls for 3 minutes, add one provolone slice to each bottom and return them to the oven for 1 minute.
Slice the rested beef very thin across the grain, fill the rolls and serve each sandwich with a cup of hot strained jus.
