I went to several stores looking for the cajun sausage and creole tomato sauce. I don't know, but the restaurant probably special order these items from a specialty stores, even the butcher said he hadn't heard of such a sausage. He suggested that I should just get some ground pork and season it with cajun seasoning. As soon as he said that I had a "light bulb moment." I went to the spice shelves and bought a bottle of cajun seasoning and decided not to use sausage.
To my amazement, it tasted good! Except my version is slightly drier because I didn't use tomato sauce, and I could taste a little touch of vinegar. Other than that it came out good. Next time I'll get some sausage and use tomato sauce instead of tomato salsa. I will do some more experimentations on this recipe, until then.......eat and enjoy life! Bon Appetit!!
