I plan meals in advance, so unless there is a change in plans, I rarely would look in the fridge for lunch.
In my freezer I havebread, bread rolls, cold meat, sausages etc etc and in the larder a range oftinned food: soup, baked beans, tinned fish and ratatouille and tomatoes. The fridge hardly features in inpromptu meals.
I have just looked at what I have on the list for this week and next. We will have home-made soup on 4 days (I have a soup maker), chappati and vegetable curry, home made pizza based on a round pitta with salad, fish cake and grilled tomatoes, baked potato with cheese and colslaw or a tin of ratatouille, stuffed peppers or mushrooms with salad.
