frozen salad

I picked the kids up from Shelly's on Friday and the weather was awful! I told the kids that I would put a movie on, but they needed to be quiet and not fight. I had to drive very careful. Alli followed that statement up with "It's frozen salad!" Having no idea what she was talking about I asked her what she said, she replied, "We need to drive careful because the ice is frozen salad." Or frozen solid...whatever one you want to say:)!
