Our food is frozen because it is the most natural, healthiest way to preserve food. Using freezing as a method means we don't need to add any preservatives, gases or additives to our food.
Freezing food reduces the amount of food we throw out and is therefore a much more sustainable option.
Lastly, frozen meals in the freezer are way more convenient than fresh. It means that you will always have a meal on hand when you just don't have the time to cook!
