We have a fairly simple lunch; roast turkey, roast ham, stuffing, roast potatoes, sprouts, parsnips, and gravy. Followed by pudding and a cold sweet. I prepare the whole meal the day before: I also have an oven with a delayed start timer so that the turkey goes in the oven overnight and the oven turns itself on at about 8.00am.
I do not go near the kitchen for lunch cooking purposes until 12.00, when I put the pre-prepared veg in the oven and then again not until 12.45 when I cook the sprouts and busy around putting food on serving dishes and making gravy.
Once the meal is served I do no more food preparation until the following lunch time. There is cold turkey, ham etc, plenty of salad and plenty of bread and cheese and family members can eat when and if they want to.
It means I have a relaxed day enjoying myself with my family and nobody is made to feel uncomfortable by me rushing round martyring myself while they are not allowed to do anything.
