Add the olive oil Instant Pot, and heat for a minute. Add beef strips to cover the bottom of the pot, season with salt. Cook for 2-3 minutes per side, transferring to a clean plate.
Carefully remove the lid from the Instant Pot, then add the broccoli to the pot, mixing it in with the sauce. Simmer for 3-5 minutes, until broccoli is softened to your liking.
