What healthy snack can provide protein after physical activity?

Well usually people would get granola bars. But I wouldn't suggest that, it doesn't have that much protein. When my father was young he use to eat tuna, tuna has a lot of protein and that's a good source to get it from. Plus you can get tuna cheap instead of buying the over priced protein meals.
