Food ideas?

Just did all these workouts back to back to back and it was MADNESS 😰 but TOTALLY WORTH IT, my legs are still burning.

I want your opinion on this. What should a good snack be? Should I even eat a snack if I ate lunch around 12:36? I started the workout at like 3:18.

P.s. I do have a snack RN (glass of whole milk) but I want othwr ideas to what I should do.
