It does say example beef OR chicken, so it's unlikely the actual box will be contain more than the example picture.
It says it contains a weeks worth of food for 2 people plus some household essentials, so it will have more in it than the photo.
It won't necessarily have your favourite products, but it should have enough to stop someone going hungry. I suspect a lot of people complaining they have no food actually mean that they've run out of their preferred items and won't actually go for this though.
