Are the pouches vegan?
Many are; the aioli and a few sauces are not. Each product page lists the ingredients and allergens.
Do they need refrigerating?
Not until opened. The pouches are shelf stable — refrigerate after opening and use within the period on the pack.
How do I heat them?
In a pan over a low heat for a few minutes, or in the microwave in a covered bowl. They are already cooked, so you are only warming them.
Is this the same food as in the restaurants?
The retail range is built on the same recipes, adapted for a shelf-stable pouch rather than a kitchen.
