I dont plan i have to make sure there is food to eat in the fridge. I have Linda McCartney sausages (frozen) in the fridge as a back up if I have no food and a bag of Kale lying around (usually for a week). Eggs and mushrooms and smoked salmon so i can rustle up an omlette and baked beans. Just make sure you have some staples in so you can eat something but i dont tend to meal plan. Also my husband is on a protein rich muscle building diet, my son is mr meat and potatoes and my daughter is miss veggie sophisticate so we all eat different meals - arrrghhhhhhh!
