I cooked the sausages from raw like 80% separately then put in with the veggies to finish. I can’t remember times or temps, sorry!
I agree with the size issue, I am a single person so it’s less of an issue but I do find myself eating in courses rather than one plate with different sides. Like tonight, I ate a plate of asparagus then a bowl of potatoes then a piece of chicken. It’s ok for the moment, but I can see myself getting tired of a piecemeal dinner.
