Yes you can eat sausage rolls that haven't been in the fridge.
Sausage rolls can be left out of the fridge at room temperature for up to 24 hours.
As long as the sausage rolls have not been out of the fridge longer than 24 hours they are safe to eat.
I've kept sausage rolls out at room temperature for 24 hours before and they have remained safe to eat.
If you're not gonna eat or serve the sausage rolls within 24 hours you need to refrigerate them to prevent spoilage of the sausage.
If the sausage rolls are left out longer than 24 hours then bacteria can grow on the sausage and the sausage rolls and make you sick if you eat them.
So refrigerate sausage rolls that are not gonna be eaten or served within 24 hours.
