I do Brazilian Jiu-Jitsu on rest days (before my first meal); what would the ideal meal look like for these circumstances?

Hey all,

I think the title basically sums up my question, but just to reiterate: should my first meal be exactly the same as my other rest days (as if I didn't go to BJJ)? If not, how should it be different?

Also, for whatever it's worth, BJJ feels much more like "cardio" than resistance training from a physical standpoint. Should I be looking for simple sugars immediately afterward?

Thanks!
