we have two different ways of doing sausage rolls - for the ones DH takes to work, they need to be cooked before freezing so he can reheat in little portable oven in the truck - for ones to be used at home, they can be frozen easily enough without cooking - they just take a bit longer to cook and HAVE to be heated in the oven - no micro cheating!

generally we mix sausage mince, finely chopped onion, and Season All - Spicy together, then make the sausage rolls on puff pastry - make sure to use milk to join the pastry (make it sticky) and poke little holes in the top

when we're making them with more veg, you can put carrot, capsicum etc in them - but you have to make sure to grate them up REALLY small - you don't want a sausage roll that is just a chunk of veg!

there are lots of other permutations (my cousin makes them with pork, veg, chilli etc) - but they are the options DH and I use
