I based this recipe on a Cajun Jambalaya recipe that I love. No tomato is one of the things that makes this Cajun. As with it's Creole cousin it features the "Trinity", onion, celery and green bell pepper. It can be made as hot as you like by using more Cayenne or Tabasco sauce. The Ritz crackers may seem like an odd pairing but, the buttery, salty flavor enhances the flavor of this dish.
