Can you substitute chorizo sausage for andouille?
As a former chef, I make a Portuguese dish with choricuo sausages, potato’s and white beans, it will be fine, the pre cooking is fine but the fat does add alot of flavour, the only real difference between the 2 sausages is the andouille is smoked were the Spanish and Portuguese sausages is not, you can brown it for a nice rich flavour, and cook the onion for you beans in the fat and caramelize them for even more flavour and taste.
