First of all, packaged gravy???? There's no way that's OM NOM material.
Second, yes, some of us southern americans do eat gravy with our "freedom fries". However, it's a cream/white gravy, not brown. We eat brown gravy with roast beef or other beef dishes. That brings me back to point one. You NEED meat bits and animal fat to make a proper gravy. It doesn't come from a package!!
Yes, I have heard of poutine, but I didn't know it had cheese curds in it though.
