I am an executive chef that must make a career change due to back surgery after 30 years of experience what would be a good career change I have a chance to take classes on line to be retrained?

Discover what you like about being a chef and find other jobs that transfer into that. Being a consultant would be good. Also, get a career book like "What color is your parachute?" or something like that. I got a copy from the public library.
