In something over two years as a Swiss wife, I've also learnt how to keep mealtime leftovers to a minimum. Before starting to prepare a meal, I estimate how much will be needed to let the family eat their fill without stuffing themselves (overeating is unhealthy, after all).
做了二年多的瑞士媳婦，我還學到了儘量不要有廚餘的方法：準備餐點之前衡量一下，能讓家人吃八九分飽就好了（飲食過量不利健康呢）。
