I'm sure you have experience in feeling thirsty or some may even develop allergy after dining out. When it is sometimes difficult to avoid dining out, we definitely have full control over what to serve to our loved ones when eat in.
Say NO to preservatives and additives does not mean we eat bland, tasteless food. In fact, it is the other way around - you finally can tell what is the taste of fresh ingredients, and how every food carry distinguish flavours that are nurtured by our nature.
I use Thermomix but there are other brands of powerful all-in-one food processors that can do the same job too.
