The basic difference is that quiet can mean little or no noise, but silent means ZERO noise. If you describe somebody as quiet, it means that person doesn't talk very much. People can also talk quietly (with a very low volume) but itís impossible to talk silently!
The Collard vegetable appear to have been cultivated as far back as during the Roman Empire. Its roots can be traced back to parts of Africa and Brazil. It continued as a main staple food in the African American diet. collard greens should be cleaned as the same way as you do in any other greens like spinach. Wash the whole bunch in cold running water for few minutes until the dust, dirt rid off from the leaves and then rinse in salt water for about 30 minutes to kill any germs, cysts, and to rid off any residual pesticides.
