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!
