Put the Instant Pot on saute. Add olive oil and saute chorizo/sausage. Take out chorizo.
Mix the seasoning blend with the pork slices. Saute the pork slices. Add more oil if necessary. Take out the pork slices.
Add the vegetables, one at a time. Start with the onion, then garlic, then celery, then the bell pepper. Once the vegetables are soft, add the tomato sauce.
Add back the pork slices, the rice, then the broth. Mix everything together.
Taste to see if more salt is needed (this depends on your broth), and add more salt until you find your preferred salt level.
Put back the lid of the Instant Pot and set to high pressure cook for 8 minutes. Natural release for at least 10 minutes, then quick release the rest of the remaining pressure.
Open the lid, add the chorizo/sausage, and mix it together with the rice.
Serve on individual plates, topped with more chorizo and scallions. Enjoy.
