New WWE Champs -- How'd We Celebrate??? Sushi & Miller Lite!!! (VIDEO)

Newly crowned WWE champs Roman Reigns and Charlotte Flair are about to answer the most important question about being a brand new champion ... WHAT DO YOU EAT TO CELEBRATE?!

We got the duo leaving NBC in NY and tossed the question ... and the Wrestlemania 32 conquerors both fessed up immediately ... although they were on totally opposite ends of the spectrum.

Check out the clip -- Roman played the part of the simple man while Charlotte -- yes, Rick's daughter -- talked about the fancy food she ate on the jet to NYC (Nature Boy would be proud).
