What does Heisman Trophy winner Lamar Jackson have in common with UFC Star Ronda Rousey? They both eat their feelings in exactly the same way ... over a heaping plate of chicken wings!!!

We got Jackson out in NYC still basking in the post-Heisman glow and asked him the question everyone secretly wants to know  ... after you win the Heisman, what do you chow on to celebrate?

That's when Lamar showed he had something in common with Rousey ... telling us he mowed down some chicken wings -- Ronda's celebratory meal of choice -- after he was handed the trophy.

It remains to be seen if Ronda will ever have a reason to eat wings again ... but if you've seen Lamar play, you know this kid is just starting to fill his trophy case.

Beware, Hooters!
