Dont' worry about "undoing" your workout. Your body doesn't work that way. Your exercise is actually the smallest portion of the calories you burn each day. You don't look at what you eat after a workout, you look at your calories in and out at the end of the day and week.
The best post-workout snacks involve protein and some carbs for quick energy. If your legs are cramping, you may have a bit of a potassium shortage. The best food in the world for that is the banana. ;) There's a reason runners love them!
As long as you're eating in your range and tracking your snacks, you can't "undo" a workout with a single meal or snack. Undoing your hard work involves overeating at the end of the day, over your maintenance range.
