In this Instant Pot Paella recipe, I used onion, garlic, yellow bell pepper, and celery as my vegetables. For my meat, I used pork slices and chorizo. You can feel free to use a different type of meat like chicken and sausage. Or shrimp and fish. If you're making seafood, however, cook the seafood first and stash it away. Don't include the seafood when you cook the rice in the Instant Pot. Just mix it with the cooked rice after. Whatever ingredients you decide to use with your Instant Pot Paella, the only thing you should always remember is your ratio of rice to broth.
