Awesome.
In the future, if you're in a situation where you can't access andouille sausage when you need it, there is an option to make it at home.
https://www.thewickednoodle.com/homemade-andouille-sausage-recipe/This recipe calls for using country style pork rips and pork fat to either make links or sausage patties. You can make a leaner version using just ground pork bought from the store, you probably already have the spices needed at home.
This would mean making gumbo with ground sausage patties instead of links, but it'll work in a pinch.
