Jambalaya is one of those all-in-one dishes where almost anything goes. Like many cajun and creole dishes, jambalaya starts with the "Holy trinity" Of onions, celery, and green bell pepper. The addition of tomatoes makes it more of a creole-style jambalaya. This instant pot version includes chicken, shrimp, and spicy andouille sausage. Feel free to omit the shrimp if you like, or replace it with crawfish, scallops, or extra chicken and sausage. Or add some extra vegetablessliced okra, thinly sliced carrots, and chopped chili peppers are just a few of the many possibilities.
