Slice flank steak into pieces so it fits in the pot and season both sides with salt & pepper. Add steak to IP and brown both sides in batches. Transfer to plate and set aside.
Add onion and peppers to the pot. Sautée 4-5 min or until softened. Be sure to scrape any brown bits on the bottom of the pot (that's flavour!). Add garlic and cook another 45-60 sec.
Add garlic powder, oregano, paprika & cumin & toss everything to coat. Sautée 45-60sec to awaken the spices. Add tomatoes, lime juice, & olives. Give everything a stir before adding steak back to the pot.
Cover the steak with the veggies, close the lid, set to sealing and cook under high pressure 45min.
Once cooked, release pressure manually and shred the steak in the pot. Adjust salt & pepper as required and add cilantro.
Serve with cauli rice and/or plantains (see my blog for recipes) and garnish with jalapeño, avocado and cilantro
