Instant Pot Instructions:

Preheat the instant pot using the Saute function. Add the ground beef & onion & cook until the beef is no longer pink, using a wooden spoon or potato masher to break down the ground beef. Remove the instant pot liner and drain excess fat, if desired, and return the pot & ground beef mixture to the Instant Pot.

Add the remaining ingredients, except the buns. Add the lid and seal and set to high pressure, seven minutes. When time is up, use the quick release.

The beef mixture will still have quite a bit of liquid in it. Press the clear button, then the saute button and simmer, stirring now and then, until reduced to the point that when a spoon is run across the bottom of the pan, the space doesn’t fill in immediately with liquid. Taste and adjust seasonings.

Serve on buns with desired accompaniments.
