Joey Fatone may be known for once singing and dancing alongside Justin Timberlake in the multiplatinum boy band ’N Sync, but now he’s cooking alongside everyday folks in their own kitchens. On the Live Well Network series “My Family Recipe Rocks,” which airs on WBIN in Boston on Saturdays at 9 p.m., the 35-year-old Fatone brings the trademark charm that has given his career remarkable durability since his teen idol days passed, from acting in “My Big Fat Greek Wedding” to competing on “Dancing With the Stars.” The food show asks home cooks to submit through its website (www.livewellnetwork.com) for a chance to have the former pop star join them in the kitchen and learn their dishes.
