Everton announced on Wednesday morning that Allardyce had left as manager after just six months at the helm.
The former England boss took over at the Toffees in November, after the departure of Ronald Koeman, with the Merseyside club sitting 13th in the standings.
Ahead of the meeting, Allardyce has hit out at a lack of "decency" after Everton pushed ahead with boardroom changes by appointing Professor Denise Barrett-Baxendale to replace Robert Elstone as CEO with Dr Keith Harris becoming deputy chairman without his knowledge.
Allardyce, also known as Big Sam, has been heavily criticised by fans for his management and Everton's style of play since he took over and the club said the decision was part of their "longer-term plan".

It's just kind of a given. "If you're not asking guys to wear heels and a dress, you can not ask me either". She added, " I get the black-tie thing but you should be able to do either version - flats or heels".
Allardyce took over the reins on November 30 a year ago, six months after leaving a similarly short stint at Crystal Palace.
Asked about the situation, Allardyce hit out at the club.
The 63-year-old said that he was "disgusted" by the behaviour of the board after they failed to inform him of the imminent changes, and suggested that his own future is likely to be decided during a meeting with club owner Farhad Moshiri today. "The catalyst for this decision is that unwarranted approach, something which the board believes has seen a significant deterioration in both focus and results to the point where the long-term future of Watford FC has been jeopardised".
Sam Allardyce has been left "shocked", "disappointed" and "disgusted" by his Everton exit.
"I've done all that I can, the backroom staff have done all that they can, and the players have done all that they can".
