Chop mushrooms ready. Fry onions, carrots and celery in a little oil. After a few mins, add mushrooms and sausage meat (if using) cook for about 10 mins on medium heat. Add salt and pepper
Add stock and passata. Stir and simmer for about 45 mins. Turn on the oven to 180. Add a bit of sauce to each lasagne sheet one at a time. Top with pecorino, roll up and put in an oven tray. Finish lasagne sheets adding to tray. Add a little extra passata on top.
Add some pecorino. Add the bechamel and spread all over. Add more pecorino if you fancy it (I did!) Bake in the oven for about 30 mins ish until lovely and golden. Enjoy :)
