Erin Andrews says working Thanksgiving Day games is a real bummer ... telling TMZ Sports her dinners don't consist of decadent turkey on the holiday anymore -- but rather, peanut butter and jelly sandwiches!!!
The FOX sideline reporter broke it all down for us at LAX ... explaining even though she has a blast getting paid to watch the NFL on the holiday -- it's still a downer.
"I mean, it stinks," said Andrews, who's been sideline reporting on Turkey Day for years and is slated to help call Thursday's Lions vs. Bears game this year. "But it is great to be able to work and watch football."
