Personally, Ive been trying to limit processed meat such as sausage due to concerns with processed meats and added nitrates. Instead I’m trying to intake high quality and premium meats during IF. Nothing wrong with the occasional processed meat but it sounds like you are proposing making sausage a staple item.
It’ll taste good but it depends what your concerns are. You can lose weight on it, but studies have demonstrated it’s carcinogenic and will cause problems. It’s also extremely high in salt in our already over salted diets so your blood pressure will suffer. I personally try to limit it.
