INSTRUCTIONS Add ground beef to the Instant Pot. Using the display panel select the SAUTE function and adjust to MORE or HIGH. Brown the meat until no pink remains. Drain fat. Transfer browned meat to a shallow dish and cover loosely with foil. Add bacon to the pot and cook until crisp. Remove bacon with a slotted spoon and set aside on a paper towel-lined plate. Add onion to the bacon drippings and saute until soft, about 3 minutes. Add broth to the pot and deglaze by using a wooden spoon to scrape the brown bits from the bottom of the pot. Put the ground beef back into to the pot and add the ketchup, worcestershire and mustard. Turn the pot off by selecting CANCEL, then secure the lid, making sure the vent is closed. Using the display panel select the MANUAL or PRESSURE COOK function*. Use the +/- keys and program the Instant Pot for 5 minutes. When the time is up, quick-release the pressure. In a small bowl, mix together cornstarch and cold water. Stir into the pot until thickened, returning to SAUTE mode as needed. Stir in bacon and cheese. Serve hot on toasted brioche buns.
