This Southern chow chow is typically made with just chopped bell peppers, green tomatoes, sweet onions and cabbage. Chow chow can be mild or hot, depending on the spice used. It can be used as you would any other kind of pickled relish. Use it as a topping for hot dogs, hamburgers or barbeque. It's also commonly used to give a little kick to a bowl of beans or a side of cornbread.
