(CNN) A coroner's inquest into the death of a 15-year-old with severe food allergies who died shortly after consuming a baguette from popular British sandwich chain Pret a Manger will get underway in London on Monday.

Natasha Ednan-Laperouse is believed to have suffered a fatal allergic reaction to sesame seeds baked into the sandwich while she was traveling with her father Nadim to France on a British Airways flight in July 2016.

The inquest will seek to establish the circumstances surrounding the death and whether any lessons can be drawn from it.

Before the inquest began, the family released a statement describing the struggle with adjusting to life since Natasha's death, which they called "a daily battle."

"As a family now of three, my wife, son and I are still trying to adjust to life without our beloved girl," said the statement by Nadim and Tanya Laperouse. "It's a daily battle and the pain is indescribable."
