U.S. Open Chicken Tender Fan Cluck You ... I'm Hawking My Cola Sauce!!!

The U.S. Open fan who caused a collective gag when she dunked her chicken tenders in soda is now making it possible for you to indulge ... and if you think the food combo makes you nauseous, check out her music video.

Alexa Greenfield, tells TMZ ... she's about to launch her new product -- Cola Sauce! She's unveiling her product 2 ways -- with a video that rivals "Thriller," and an appearance at a chicken joint.

Alexa will make a personal appearance at Hill Country Chicken in NYC on January 26 and 27. It's not just any ol' chicken joint ... it the place she bought the tenders that made her famous.

Truth be told ... the video's kinda fun. It instructs the not faint of heart on how to properly tenderize your tenders with the soda of your choice.

Alexa's going full bore ... she's launching Cola Sauce on her website next month.

With Wimbledon looming ... can fish filets be far behind?
