Oh my FIL had a host of things he couldn't eat: including pasta, mushrooms, garlic, chicken
The whole family of a school friend of mine had a tiny list of things they would/could eat.
Basically:
steak or chicken breast or sausages
with
mashed potatoes or chips
plus
carrots or peas.
No rice, pasta, fish, cheese, other vegetables, salad, tinned anything, sauces, "mucked about"...
Friend and I were sooo excited when McDonald's came to town!
But she had to have a special order or a burger in a bun and nothing else.
Later in life, her brother treated their father to a trip to Australia for the cricket.
Her DF rang Air Sri Lanka to check they wouldn't serve "foreign" food...
Oddly, they were the people who introduced me to Chinese food as a Chinese takeaway (sweet and sour chicken and chow mien) was their Saturday night meal and the only thing they ate that differed from the list above.
Years later my friend proudly told me she now ate pasta...
Plain, on the side of the plate and as a change from the usual potato dish.
