Eating AFTER workout

I know there's tons of literature and commentary on walks/exercise after eating to offset an insulin spike.

What about eating after a workout? I workout 4-5x a week on my break at work. With the time and intensity I don't want to eat lunch before my workout. Is there a significantly inherent harm in eating immediately post workout instead?

It's still typically a high protein/fat and low carb meal, if that matters
