First I peeled and cut the onions into eighths and put it into a freezer bag with oil, mustard, dried sage, black pepper, lemon juice and a splash of Worcestershire sauce. Squidged it around, then added the chicekn pieces. Left it to marinate in the fridge for over 2 days.
Then Preheated the oven to gas mark 7, put the chicken into a roasting tin, skin side up with the marinade. Put the sausages in. Sprinkled a tablespoon of fresh chopped sage over the chicken and sausages. Roasted it for over an hour, turned the sausages midway through so that they could brown evenly. Enjoyed it immensely.
