Plugin the power cord of the Instant Pot and when the LED display reads ‘OFF’ (in standby mode), press the SAUTE button (with the lid off).
Add the olive oil and the stew meat. Brown the stew meat, allowing it to sit between stirring to develop a sear on each side (note: it can be done in two batches.). Remove and place the meat on a plate or mixing bowl.
Add the garlic, onion and green pepper to the Instant Pot and sauté for 3 minutes.
Add the beef (with any accumulated juices) and all the remaining ingredients to the Instant Pot. Seal and select MEAT/STEW (which is preset for High Pressure for 35 minutes).
When cooking is complete, wait 10 minutes then do a Quick Release. Serve over rice.
