My mom is a chef. There are a lot of chefs with no business skills. I would try and get her to stay at undergrad and get a business degree playing sports for the free tuition. I would encourage her to keep cooking on her own. After college she can attend culinary school, think of it like grad school. She will be in a better position to run a successful business as opposed to be a kitchen slave for $12 an hour for the next 15 years. You need to get her to try and focus on the long term. If she changes her mind after a few summers working in kitchens she can always find another grad program.
