I am guessing that like most people diagnosed later in life, the first thought is "what will I eat"
That was until I discovered M&S thanks to a friend, 95% of their sausages are Gluten Free, their Burgers are, many of their ready meals are, and they do Chicken or fish in GF Breadcrumbs, chicken and mushroom or salmon "fishckaes" to name just a few. Many of their sauces are GF and lots of other products.
My question is - if they can make so many of their mainstream products GF and cater for us in their other ranges for the same price, why can't others do it?
