Remove the cooked sirloin to a paper towel lined plate.
Add the chopped onion to the Instant Pot, and saute until it's caramelized - or golden brown.

Add the cooked sirloin back in the Instant Pot, and add the red beans, black beans, and Ranch style beans.

Let the Instant pot build and release the pressure - this will take a few minutes to bring the Instant Pot up to pressure, then cook, and release the pressure.
When the Instant Pot is done cooking, it will beep and go to the 'OFF' setting.
Make sure all the pressure has been released by turning the pressure valve to VENTING, and make sure the FLOAT valve is down.
Open the lid to the Instant Pot, and stir the Chili.
