Instructions
Heat the olive oil in a large skillet over medium-high heat. Add the ground beef and cook, breaking it up with a wooden spoon, until browned and no longer pink, about 5 minutes. Drain off the excess fat.
Add the onion, bell pepper, mushrooms, and garlic to the skillet. Cook, stirring occasionally, until the vegetables are softened, about 5 minutes.
In a small bowl, whisk together the Worcestershire sauce, ketchup, cornstarch, and beef broth until smooth.
Pour into the skillet and stir to combine. Bring to a simmer and cook until thickened, about 2 minutes.
Season with salt and pepper. Reduce the heat to low and stir in the shredded provolone until melted.
At this point, you can refrigerate until you're ready to use. Or, you can toast the buns, make the Sloppy Joe, and serve.
