Sandra Lee has headed back to work after her successful treatment for cancer.

The TV chef and girlfriend of New York Gov. Andrew Cuomo posted a picture on Instagram on her first day back filming.

“First day back on set — am shooting with @bobbyflay. Nice to be with my brother. #foodnetwork #bobbyflay.”

Lee had a double mastectomy last May and then underwent surgery to treat an infection. She announced she was cancer-free in September.
