Preheat the oven to broil.

Set the instant pot to sauté and add the oil, beef, sliced onion and garlic. Sauté until beef is fully cooked.

Add beef broth, Worcestershire sauce, French onion soup, salt and pepper. Pressure cook on high for 3 minutes.

Manually release pressure and strain the juice into a bowl.

Once meat and onion are strained, add to a roll, top with a half slice of provolone and set sandwiches under a broiler for 2 minutes or until cheese is melted.

Serve sandwiches with drained broth as a dipping sauce.
