Diana married Prince Charles, heir to the throne, in 1981. The couple divorced in 1996 amid huge controversy with accusations of adultery on both sides.
According to Darren McGrady, a former royal chef, Diana was extremely careful about what she would eat.
A 1989 Sunday Evening Post interview claimed the princess typically began each day with grapefruit, toast and muesli.
Mr McGrady told Hello! Magazine Diana had two specific favourite meals she would often eat.
The first, for lunch, was bell peppers filled with mushroom, rice, courgette, mozzarella and Parmesan cheese.
This was typically accompanied with smoked tomato pepper sauce
Another was “an Egg Suzette which was a baked potato scooped out with wilted spinach in the bottom and a poached egg on top and then a little hollandaise sauce, a tiny amount, with some potatoes piped around the edges”.
In 1981 Diana’s office was contacted by a Johannesburg care home which asked her to contribute a favoured meal for a new recipe book.
Oliver Everett, her private secretary, revealed the princesses’ submission in January 2020.

Mr McGrady said: “The Princess never ate much red meat.
“She never ate beef, never ate pork, occasionally she’d have lamb when she was entertaining guests but for the most part it was chicken, fish or vegetarian options.”
The former cook did say Diana would enjoy a favourite dessert, bread and butter pudding, on occasion.
He said: “She would have a small portion every now and then.
“And only when William and Harry were at home; she wouldn’t request it when she was alone.”
Princess Diana was tragically killed in a Paris car crash on August 31 1997.
